GeoStudio 2021 R2

GeoStudio 2021 R2 (82.1 MB)
version 11.1.0.22070
Requires maintenance through January 2021

Below are the changes made since the previous release.

Highlights

    GeoStudio 2021 R2 expands the breadth of problems it can analyze into tailings storage, reinforced earth, open pit and underground excavations, and tunnelling, by adding the NorSand material model and field stress definition, among other improvements.

    • The NorSand material model can be used to analyze tailings storage facilities, reinforced earth, and many other classes of geotechnical problems.

    Field Stresses can be defined in a SIGMA/W In Situ analysis to tackle open pit excavations, underground excavations, and tunnelling.

    BUILD3D changes include easily scaling, translating, and rotating imported DXF and DWG files, and viewing or exporting isosurface plots and other results.

    SLOPE/W reinforcement libraries have been expanded.

    • SIGMA/W and SEEP/W solvers boast increased speed for many classes of problems.

    GeoStudio 2019 R2 introduces two new products, SEEP3D and BUILD3D, along with continued improvements to working with multiple geometries within a single project file.

    SEEP3D can be added to SEEP/W to perform three-dimensional groundwater flow analysis. SLOPE/W can perform stability analysis of cross-sections using pore water pressure computed from the SEEP3D analysis.

    BUILD3D is a feature-based 3D geometry creation tool for use with SEEP3D.

    Improvements to multiple geometries: continuing on GeoStudio 2019's ability to combine multiple geometries in a single project file, GeoStudio 2019 R2 displays geometries in the analysis tree view, and simplifies managing geometries with the Define Project command (previously called Define Analyses). Additionally, geometries can be edited and materials assigned independent of any analysis.

All Products

  • Feature: Geometries are now displayed in the analysis tree view.
  • Feature: It's now possible to create and edit a geometry without first creating an analysis.
  • Change: Dimension (1D, 2D, 2D Axisymmetric, 2D Plan, and 3D) is now a property of the geometry rather than the analysis.
  • Feature: Geometry dimension can be selected directly from the Start Page when creating a new file.
  • Feature: Materials can be created when working within a geometry, and assigned a color and a name.
  • Feature: Material assignment can be done when working directly in a geometry. Analyses subsequently created under that geometry will initially have the same material assignments.
  • Feature: DXF and DWG files can be imported directly into a geometry.
  • Feature: A new "File - Delete Results" command has been added, to make file sizes smaller by deleting all computed results.
  • Feature: Vector lengths are specified in model units instead of screen units.
  • Change: Some keyboard shortcuts were changed to avoid duplicate shortcuts in menus.
  • Bug fix: When importing regions from DWG or DXF, if a new region completely covers an existing region, the existing region becomes invalid.
  • Bug fix: Scrollbars become disabled but don't disappear after being in Page Layout.
  • Bug fix: When importing a DWG or DXF and using the "Translate horizontal to 0" and/or "Translate vertical to 0" options, non-geometry items in the source file were not being ignored, so the geometry was not moved the correct distance.
  • Bug fix: GeoStudio crashes in Draw Graph when clicking in the graph window.
  • Bug fix: The mesh is not regenerated after deleting a line with interface elements, thus leaving a gap in the mesh. This bug is a regression introduced in GeoStudio 2018.
  • Bug fix: In some cases, a boundary condition is applied to a different line than the one that is clicked on.
  • Bug fix: GeoStudio crashes when displaying some large meshes.
  • Bug fix: Ground surface lines disappear after using Undo until the file is re-opened.

SLOPE/W

  • Feature: Define Grid and Radius and Define Left and Right Block now highlight the portions of the grid that are being edited as you tab through the dialog box.
  • Bug fix: The "Tolerable difference in F of S" and "No. of complete passes per point insertion" fields have been removed from the optimization settings, as they were no longer being used.
  • Bug fix: "Couldn't match clipboard data to list columns" error when pasting into Define Point Loads.

10.1.1.18972

    This is a minor release to GeoStudio 2019 R2, primarily focused on improvements to BUILD3D but including some features and bug fixes for all GeoStudio products. It's recommended everyone upgrade whose maintenance covers this release.

All Products

  • Feature: Materials can be created and applied to regions in the context of a geometry as well as an analysis.
  • GeoStudio becomes unresponsive (hangs) if a solve is restarted immediately after stopping it.
  • GeoStudio crashes in print preview if an analysis was deleted after the current analysis was solved.
  • Windows no longer resize or display properly after an Undo or Redo action changes the current analysis.

GeoStudio 2019

GeoStudio 2019 (80.5 MB)
version 10.0.3.18569
Requires maintenance through Dec 2018

Below are the changes made since the previous release.

History

    • version 10.0.0 - December 10, 2018 - This is the initial release of GeoStudio 2019.

    • version 10.0.1 - February 12, 2019 - This update fixes a few specific issues. We recommend upgrading for everyone whose maintenance covers this release.

    • version 10.0.2 - April 3, 2019 - This update completes the Spanish and German translation, and fixes a few specific issues. We recommend upgrading for everyone whose maintenance covers this release.

    • version 10.0.3 - June 25, 2019 - This update fixes a few specific issues. We recommend upgrading for everyone whose maintenance covers this release.

Highlights

    GeoStudio 2019 gives you the ability to analyze several different cross-sections in a single file; it simplifies working with reinforcements; and it more easily integrates with 3D CAD products through improved DWG/DXF import.

    We recommend upgrading for everyone whose maintenance covers this release. Keep in mind that even though the file format has changed between this release and the previous, GeoStudio 2019 will still be able to open older files and examine computed results. GeoStudio 2019 will install side-by-side with any other GeoStudio versions you already have installed.

    The major new features include:

       • Improved reinforcement load definition: Define reinforcement properties separately from the lines to which they are ascribed. Reinforcement lines can be snapped to the ground surface, so that they move with the ground surface.

       • Reinforcement sets: Draw, orientate, and space multiple reinforcement lines simultaneously, and associate the entire set with a particular reinforcement.

       • Multiple geometries: Each analysis branch can operate on a different "geometry", providing the ability to vary slope angles, geology, and mesh attributes if conducting a finite element analysis.

       • Improved workflow with 3D CAD files: Import DWG files of cross-sections created by 3D CAD applications such as Civil 3D and Leapfrog Works: materials and regions can be created, the geometry simplified and translated to the origin. Import MicroStation DGN files as sketch pictures.

       • Improved sketch: Embed pictures right in the .gsz file so they are not blank after emailing a file; give background colors and borders to text and tables, and control their alignment.

       • 64-bit: Handle larger analyses on 64-bit operating systems. The entire GeoStudio application is now 64-bit. (A 32-bit installer is available for older 32-bit operating systems.)

All Products

  • Feature: Multiple geometries: all analyses at the root of the analysis tree can be assigned a different "geometry", or different regions. Experiment by varying slope angles, varying geology, varying mesh density, or group related projects in a single .gsz file. All geometries in a .gsz can use the same materials and boundary conditions, but will have separate regions, graphs, and sketch objects. Use the new "Geometry" tab in Define Analyses, and the "Clone Geometry" command, to work with multiple geometries.
  • Feature: The File Import command allows importing materials from DWG/DXF layer names. Each layer selected for import can be used as the name of a material, and all regions imported from closed polygons on that layer will be associated with that material. The layer color will be used as the material color.
  • Feature: The File Import command can simplify the regions that are imported by removing unnecessary points along straight lines. Select a simplification level from 1-10. This simplifies the mesh for finite element analyses, and slice discretization in SLOPE/W analyses, and can thus make GeoStudio more responsive working with large, complex domains, as well as solving faster.
  • Feature: The File Import command can translate the imported regions along the x axis so the leftmost point is at y=0, and/or along the y axis so the bottommost point is at x=0, in order to have more readable coordinates.
  • Feature: The Sketch Pictures command can import MicroStation DGN files as background pictures.
  • Feature: With the Sketch Pictures command, you can choose to link to pictures (which is what previous versions of GeoStudio do) or to insert (embed) them in the .gsz. Inserted pictures will cause the .gsz file to be larger, but means anyone who opens the .gsz will see the pictures.
  • Feature: The Sketch Pictures command allows sizing and positioning pictures by typing in coordinates instead of only using the mouse.
  • Feature: The Sketch Text dialog box has been split into two tabs, one for the text itself and a second for text properties.
  • Feature: The Sketch Text command allows choosing the anchor point, to better align text that varies in width or height.
  • Feature: The Sketch Text command allows defining a colored border around text.
  • Feature: The Sketch Table command allows choosing the anchor point, to better align tables that vary in width or height.
  • Feature: The Sketch Table command allows separately setting the font colors and background colors for cells and headers.
  • Feature: GeoStudio is a completely 64-bit application, allowing it to access more memory and thus handle larger or more complex analyses. A 32-bit installer is available for older 32-bit operating systems.
  • Bug fix: GeoStudio can crash in Results view if analyses have been deleted.
  • Bug fix: In Draw Graph, subdomain cross section graph locations do not include secondary nodes.
  • Bug fix: AutoCAD files with minor variance in the geometry 3D planes cannot be imported since they aren't considered coplanar. GeoStudio displays an error indicating that multiple planes exist in the file. The coplanar tolerance has been relaxed to allow for minor variance in the plane normal vectors, allowing slightly non-coplanar geometry to be imported.
  • Bug fix: Modify Objects does not work with Sketch Material Tables or Sketch Boundary Condition Tables.
  • Bug fix: Template files do not work properly if they include a mesh or a dataset (files created using such a template would not include the dataset or the mesh).
  • Bug fix: When a .gsz file is exported or downgraded, datasets and the mesh could be lost in the process.
  • Bug fix: When exporting to DXF or DWG, color-filled entities show a mesh of triangles over the color fill.

SLOPE/W

  • Feature: Reinforcement properties are defined and named using the new Define Reinforcements command. The layout and labelling of the dialog box has been improved as well.
  • Feature: Reinforcement lines are added to the drawing using Define Reinforcement Lines or Draw Reinforcement Lines. The reinforcement line is the starting coordinate (typically at the ground surface) and the angle and length of the reinforcement. Multiple reinforcement lines can be associated with a single named reinforcement.
  • Feature: Reinforcement lines can be snapped to the ground surface, such that they move in response to changes to the surface geometry.
  • Feature: Draw or Define Reinforcement Sets to evenly distribute a large number of reinforcement lines along a slope.
  • Bug fix: View Object Information shows incorrect values for geosynthetic reinforcements for the Required Length, Pullout Force, Pullout Force Per Length, and Governing Component fields. The values in Draw Graph are correct.
  • Bug fix: In Sketch Material Table, not all available fields are shown in the list of fields.

QUAKE/W

  • Bug fix: In Sketch Material Table, not all available fields are shown in the list of fields.

TEMP/W

  • Bug fix: In Draw Contours, when the visible units for temperature differs from the units of computation, the increment value is incorrect.

CTRAN/W

  • Bug fix: In Sketch Material Table, not all available fields are shown in the list of fields.

GeoStudio 2018 R2

GeoStudio 2018 R2 (10 MB)
version 9.1.2.17441
Requires maintenance through May 2018

Below are the changes made since the previous release.

History

    • version 9.1.0 - May 24, 2018 - This is the initial release of GeoStudio 2018 R2.

    • version 9.1.1 - August 17, 2018 - This update fixes a few specific issues. We recommend upgrading for everyone whose maintenance covers this release.

    • version 9.1.2 - December 20, 2018 - This update fixes a few specific issues. We recommend upgrading for everyone whose maintenance covers this release.

Highlights

    GeoStudio 2018 R2 builds on GeoStudio 2018, extending features added to previous releases.

    We recommend upgrading for everyone whose maintenance covers this release.

    The major new features include:

       • Combine full and basic analyses in one file: Unlock the power of integration by combining analyses created with a basic license and a full license in the same file. For example, combining a full SLOPE/W analysis with a basic SEEP/W analysis allows the stability analysis to use pore-water pressure conditions computed from a steady-state finite element seepage analysis.

       • User-defined reinforcements: Model a wide range of reinforcements by defining them as a function of force vs. distance.

       • Analysis tree: Clone or delete an entire branch of analyses.

       • Dimensions: Sketch aligned, linear, and angular dimensions.

       • SLOPE/W graphs: Additional graphs for probabilistic analyses and for optimized slip surfaces.

       • Tables: Easily add material and boundary condition tables to your drawing.

       • Sketching: Streamlined workflow when working with sketch objects.

       • Performance: Improved performance and memory consumption when working with large projects.

       • AutoCAD 2018 files: Import files created in AutoCAD 2018 or 2019.

All Products

  • Feature: A GeoStudio project can now contain analyses with full licenses as well as other analyses using basic licenses. For example, a full-featured SLOPE/W analysis can obtain pore-water pressures from a basic SEEP/W analysis in a single project.
  • Feature: The new "Clone Branch" command will clone an analysis and all analyses beneath it.
  • Feature: The new "Delete Branch" command will delete an analysis and all analyses beneath it.
  • Feature: Sketch aligned dimensions (parallel to the object being dimensioned), linear dimensions (showing the horizontal or vertical dimensions of a slope), or angular dimensions.
  • Feature: Dimensions connected to points will resize as points are moved.
  • Feature: Orthogonal snapping: Holding the Shift key while drawing restricts cursor movement to the X or Y axes. Without the Shift key, lines that are nearly horizontal or vertical will snap to horizontal or vertical.
  • Feature: The new Sketch Materials Table and Sketch Boundary Conditions Table commands quickly add a table of materials or boundary conditions to the drawing.
  • Feature: Sketch commands allow changing properties or typing exact coordinates while sketching.
  • Feature: Sketch Arc now allows editing of the arc's center coordinates, radius, start angle and end angle.
  • Feature: Move text while sketching it (no need to use Modify Objects).
  • Feature: Sketch Text and Modify Sketch Text have been combined. To edit existing text, use the Sketch Text command and click an existing text block.
  • Feature: The Modify Sketch Objects command has been removed. Sketch objects can be edited in their respective Sketch commands. To edit the properties of a line, for example, use the Sketch Lines command and click an existing line.
  • Feature: Improved memory consumption when contour results.
  • Feature: Improved memory consumption viewing results.
  • Feature: Improved performance of displaying vectors.
  • Feature: Import files created in AutoCAD 2018 or 2019.
  • Feature: Font sizes can be set independently for dimensions, axis numbers, and axis labels.
  • Feature: Errors during the calculation of a spatial function will now be displayed in the Define Spatial Function dialog.
  • Feature: A notification is now displayed on the start page if a license's maintenance will be expiring soon.
  • Feature: Add-Ins can use functions defined in the project file.
  • Change: It is no longer possible to change "units of computation" under the Project Properties. Instead, pick a template that uses the correct units when creating a new file. You can also use the View Units command to change which units are displayed.
  • Change: In Define Functions, when changing the function type (such as from spline to step), properties in common between the two function types (such as the Cycle checkbox) will be carried over to the new function.
  • Change: The Sketch Arrows and Sketch Double Arrows commands have been merged into the Sketch Lines command.
  • Change: Moved the Define - Replace in Analyses command in the menu to group it with Define - Analyses.
  • Change: Improvements were made to translations.
  • Bug fix: A function imported from a .gsz file that uses different units of computation than the destination file ends up with incorrect values because units do not get converted.
  • Bug fix: GeoStudio would not accept x-y coordinates pasted into Define Points.
  • Bug fix: Licenses cannot be activated if the username includes certain non-Latin characters. This error is displayed: "No response from the server. Check that you have a network connection. (Error 514009)"
  • Bug fix: Some error messages in Define Functions display incorrect values because they are being displayed using the wrong units.
  • Bug fix: Using Match Scale on a Sketch Image using the mouse or typing in a value with units results in an error or invalid values.
  • Bug fix: GeoStudio may crash when changing to an analysis using the Analysis Toolbar when no license is available.
  • Bug fix: GeoStudio crashes when interacting with the menus or toolbars while some system dialogs (such as Open File) are displayed.
  • Bug fix: Files with many chained analyses may crash in Results View.
  • Bug fix: GeoStudio crashes when opening files on workstations with new Intel Xeon CPU supporting AVX-512 instructions
  • Bug fix: GeoStudio will crash if the Reference Scale or Vertical Exaggeration values are deleted.
  • Bug fix: Incorrect keyboard shortcuts in the File menu for the Most Recently Used files list.
  • Bug fix: When opening a file created by GeoStudio 2016 or earlier, flow paths are removed, and an upgrade message indicates "There is no equivalent [feature] in the later version", which is incorrect.
  • Bug fix: After selecting File Print, docked windows appear blank.
  • Bug fix: Some functions do not get downgraded correctly when exporting as a GeoStudio 2016 file.
  • Bug fix: Windows no longer resize properly after a Redo action changes the current analysis.

SLOPE/W

  • Feature: The new user-defined reinforcement type provides a flexible option for modeling a wide range of structures with spatially variable shear resistance.

Highlights

    GeoStudio 2018 is a major new release of GeoStudio, introducing power and flexibility by combining multiple physical processes in a single analysis, among other improvements.

    We recommend upgrading for everyone whose maintenance covers this release, but because of the number of major changes between GeoStudio 2018 and GeoStudio 2016, we suggest you schedule some time to upgrade your older files. GeoStudio 2018 will install side-by-side with any other GeoStudio versions you already have installed.

    The major new features include:

    Improved multi-physics capabilities

       • A new rigorous finite element solver used by SEEP/W, TEMP/W, AIR/W and CTRAN/W features new multi-physics capabilities and faster solve times.

       • In a single analysis, ability to simultaneously compute and/or couple water transfer, air transfer, solute transfer, gas transfer, and heat transfer processes. Use the new Physics tab in the Define Analyses window to choose which physical processes to enable in the same analysis.

       • Simulation of a broader range of engineering problems including climate effects on the ground surface, groundwater flow in freezing and thawing soils, and movement of solutes and gases in the subsurface.

    New climate-interaction boundary conditions to simulate atmospheric coupling

       • In SEEP/W, the Land-Climate Interaction boundary condition simulates water transfers at the surface given climate and vegetation data.

       • In TEMP/W, the Surface Energy Balance boundary condition simulates energy exchange over the ground surface.

       • Boundary conditions can be used together to simulate coupled hydraulic and thermal responses of the ground profile to atmospheric conditions.

       • Boundary condition data can be imported using the new Data Set feature. This allows for easy selection of data files containing field measurements (e.g., from weather stations), including column selection and unit conversion.

    True 1D finite element analyses

       • SEEP/W, TEMP/W, AIR/W and CTRAN/W now include true 1D modeling, which significantly speeds up 1D analyses that use many time steps.

       • One-dimensional and two-dimensional analyses can share the same mesh and be run in the same project.

    New Plan View definition

       • Plan view now supports a variable aquifer thickness using spatial functions, allowing for new types of plan view problems to be analyzed.

    Comprehensive unit conversion and support

       • GeoStudio now offers considerable flexibility for selecting units for input and display.

       • Default display units can be selected for individual or groups of parameters.

       • When a value with units is entered for a parameter into any edit control, the number is converted to the selected units for the parameter.

    Enhanced graphing capability

       • Graphs can be set up and computed during solve time, allowing for rapid graph display.

       • Results can be plotted within any subdomain, allowing for element-based parameters to be adjusted at nodes for plotting purposes. Subdomain plots can provide insight on flow through an internal node over time; consequently, flux sections are no longer required.

       • Cumulative parameters are now accumulated during solve time, significantly speeding up graphing of these parameters.

       • Data parameters have been reorganized in the dialog to make it easier to find the parameter to plot.

    New 64-bit solvers

       • Each solver in GeoStudio 2018 has new 64-bit processing support, enabling GeoStudio to now solve projects with many more analyses and denser meshes. The 64-bit solvers also offer improved performance when solving individual analyses or calling Add-In functions.

       • Improved multi-threading support offers performance gains when solving many analyses simultaneously on modern CPUs.

       • Solvers can now be stopped mid-computation and restarted without having to restart the analysis from the beginning.

    Improved transient analyses

       • Multiple options are now available for defining time increments in transient analyses; the time increment length or the number of time steps over the given period may be specified.

       • Time-based mass, volume, and energy boundary conditions such as water rate, heat flux, and mass flux are now integrated across a time-step, ensuring perfect mass and energy conservation at the boundary and improving overall accuracy of the solution.

    GeoStudio Basic now bundled with all products

       • Purchasing a Full Feature license for any product will now provide access to a Basic license for all other GeoStudio products, allowing for greater product integration.

       • For example, the owner of a full SLOPE/W license will now be able to complete a steady-state water transfer analysis using SEEP/W to define the spatial variability in pore water pressures.

    New German language support

       • The GeoStudio user interface can now be run in German.

       • Previous language translations have been improved, including Spanish, French, Chinese, and Portuguese.

    New engineering examples and books

       • Additional examples are available representing a wider range of geotechnical and earth science problems.

       • The engineering books have been updated to reflect the new features and functionality of GeoStudio 2018. The finite element flow products feature a new book called "Mass and Heat Transfer Modeling with GeoStudio".

    Improved Add-In support

       • Add-In functions can now be stateless, allowing for significant performance improvements during the solve process.

       • Add-Ins can now be written using the latest versions of Microsoft Visual Studio (e.g., 2017).

       • Add-Ins can be written as 32-bit or 64-bit. They now require .NET 4.0.

       • The Add-In SDK document and examples have been updated to reflect the new features.

  • Bug fix: The parameter controls in Draw Contours and Draw Graph, and the Parent Analysis selection in Define Analyses, do not work properly: other properties should change but don't when a new value is selected. This bug is a regression introduced in GeoStudio 2018 version 9.0.3.
  • Bug fix: In some cases the time ranges of nested analyses are incorrect.
  • Change: Changes were made to various translations based on customer feedback.

SLOPE/W

  • Bug fix: The factor of safety legend is not visible when a file is re-opened.
  • Bug fix: GeoStudio may crash while solving an analysis with the "Optimize critical slip surface location" option selected.
  • Bug fix: View Preferences always uses the term "ODF" even when Degree of Utilization is selected as the Partial Factor Display option.

SEEP/W

  • Feature: "Subdomain graphs" were introduced in GeoStudio 2018 as a replacement for "Flux Sections" in previous releases. A "Subdomain cross section" tool has now been added to the Set Locations mode in the Draw Graph command. A “subdomain cross section” is created by drawing a polyline on the domain. Elements intersected by the polyline form the subdomain. Nodes are automatically selected along the left side of the subdomain. The “subdomain cross section” tool makes it possible to quickly create “subdomain graphs” of the amount of heat or mass flowing past a section within the domain.
  • Feature: When opening a file created by GeoStudio 2016 or earlier, Flux Sections will be converted to subdomain graphs.
  • Change: Using View Result Information, the properties of a flow path have been changed: Average Speed has been replaced with Average Flux, and Travel Time has been removed for steady-state analyses.
  • Bug fix: Flow Path lines cannot be drawn if no storage function has been defined.
  • Bug fix: In a Land-Climate Interaction boundary conditions, Calculated Snow Depth functions are not calculated properly if the air or precipitation functions use the "Cycle" option.

TEMP/W

  • Feature: The ground surface temperature can now be modeled directly using an n-factor boundary condition. The n-factor boundary condition uses a ratio of the ground surface and air freeze/thaw indexes to calculate the simulated ground surface temperature.
  • Change: Using View Result Information, the properties of a flow path have been changed: Average Speed has been replaced with Average Flux, and Travel Time has been removed for steady-state analyses.
  • Bug fix: Flow Path lines cannot be drawn if no storage function has been defined.

AIR/W

  • Change: Using View Result Information, the properties of a flow path have been changed: Average Speed has been replaced with Average Flux, and Travel Time has been removed for steady-state analyses.
  • Bug fix: Flow Path lines cannot be drawn if no storage function has been defined.

9.0.5.16316

    This update fixes a few specific issues. We recommend upgrading for everyone whose maintenance covers this release.

All Products

  • Change: Improvements were made to various translations based on customer feedback.
  • Change: Online help content has been updated.
  • Bug fix: Licenses cannot be activated if the username includes certain non-Latin characters. This error is displayed: "No response from the server. Check that you have a network connection. (Error 514009)"
  • Bug fix: When typing units while changing values in Page Layout fields, the value may change.
  • Bug fix: In some cases Draw Regions and Import Regions will produce incorrect regions when multiple overlapping regions are drawn or imported.
  • Bug fix: GeoStudio crashes when opening files on workstations with new Intel Xeon CPU supporting AVX-512 instructions
  • Bug fix: A "syntax error" message is displayed when changing the source of the initial conditions of an analysis with a basic license.
  • Bug fix: When opening a file created by GeoStudio 2016 or older, flux sections correctly get converted to graphs, but the upgrade log does not mention them.
  • Bug fix: The duration of a steady-state analysis changes from 0 to 1 when opening a file created by GeoStudio 2016 or earlier.
  • Bug fix: In Draw Graph, when selecting a subdomain, in some cases no nodes are selected.
  • Bug fix: Windows no longer resize properly after a Redo action changes the current analysis.

SLOPE/W

  • Bug fix: For staged analyses, the shear resistance graph data for non-critical slip surface is incorrect. This bug does not affect the computed FOS.
  • Bug fix: In Define Analyses, on the Slip Surface tab, the "tension crack angle", "filled with water", and "unit weight of water" fields are blank. This bug was a regression introduced in version 9.0.4.
  • Bug fix: GeoStudio crashes in Define Analyses when creating a new SLOPE/W Analysis - SIGMA/W Stress or QUAKE/W Stress or QUAKE/W Newmark Deformation, if the current analysis is a SLOPE/W analysis.
  • Bug fix: Slip surface contours now indicate the contour units for overdesign factor analyses.
  • Bug fix: The Draw Graph dialog does not show the correct dependent variable for a factor of safety (FOS) or Overdesign Factor (ODF) analysis.
  • Bug fix: View Slice Information shows Overdesign Factor when the analysis preferences are set to Degree of Utilization.
  • Bug fix: When changing view preferences between displaying factor of safety and overdesign factors, duplicate menu and toolbar items appear for contour labelling and slip surface display.
  • Bug fix: When using partial factors and having the display format set to degree of utilization, slip surfaces with errors incorrectly show as 0.001 instead of E999 (for example).
  • Bug fix: Data in the Draw Probability graphs may be incorrect when changing result times.

SEEP/W

  • Bug fix: The solver crashes and reports the error "Failed Windows system service call to WriteFile(): The pipe is being closed" in the solve manager window in certain cases when a boundary condition has been assigned to a portion of the mesh that has only null elements (no material properties).

Highlights

    GeoStudio 2016 is an easy upgrade from GeoStudio 2012. We recommend upgrading for everyone whose maintenance covers this release. (Maintenance is required through August 2016.)

    The major new features include:

    Page Layout:

    • Sketch objects (lines, text, pictures, etc.) in paper space that only appear when printing.

    • Page Layout sketch items are displayed over the model, in either Define or Results views.

    • Create or import Page Layout templates.

    Enhanced Model View:

    • Page size and extents no longer need to be defined until printing or going to Page Layout view.

    • Infinite model space.

    • Improved grid lines rather than grid points.

    • Red and green reference lines at x=0 and y=0.

    • "Go to coordinate" command to quickly jump to a coordinate.

    • "Pan" command to pan the model (or use the middle mouse button).

    • Previously there were separate horizontal and vertical scales. Now there is a "reference scale" (used for font sizes and symbol sizes) and a "vertical exaggeration".

    Printing:

    • Print directly from the new Page Layout mode.

    • Select multiple analyses to print simultaneously.

    • Select page size and orientation.

    • Fit to page or tile across multiple pages.

    • Print preview.

    Assign Properties Across a Set of Analyses:

    Check the "Apply to multiple analyses" checkbox in Draw Materials and other modes to assign or remove properties in multiple analyses simultaneously:

    • Materials

    • Boundary conditions

    • Beams

    • Bars

    A status column shows what changes were made.

    Replace Properties in SLOPE/W Analyses:

    Properties or objects from one SLOPE/W analysis can be copied to other analyses using the new KeyIn - Replace in Analyses command. For example:

    • Slip surface definition,

    • Pore water pressure,

    • Point loads,

    • Anchors,

    • and more.

    A status column shows what changes were made.

    Material Property Table:

    The material property table in Sketch Text now displays as a proper table, including:

    • Headers

    • Column alignment

    • Material color

    • Material name

    • Other properties

    Modify Sketch Properties:

    • A new Modify Sketch Properties command allows modifying properties of text, lines, dimensions, circles, arcs, pictures, and axes after drawing them.

    • Objects may be displayed in only specific analyses.

    • Type exact coordinates.

    Portuguese: GeoStudio is now available in Brazilian Portuguese in addition to English, French, Spanish, and Chinese.

  • Feature: Select the analyses in which to replace the objects.
  • Feature: Hit Apply or OK to replace the objects. All objects of that type in the target analyses will be deleted, then replaced with copies of all objects from the current analysis.
  • Feature: A status column shows if the replacement was successful, and if it failed, also shows the reason for the failure.
  • Material Property Table

    Material property tables can be added to a drawing using Sketch Text - Insert field - Materials - Show as a table. Previously the "table" was quite simple, and columns frequently did not line up properly.

  • Feature: Column alignment has been fixed.

  • Feature: Select a template from a dropdown list on the Start Page, then click a product name, to create a new file from that template.
  • Feature: Simplified the File New dialog.
  • Import and export

  • Feature: When exporting an analysis to DXF or DWG, the font specified in View Preferences will be used for all exported text.
  • Bug fix: Importing a DXF or DWG as a background sketch image will scale improperly in some cases. This typically occurs when the imported file included text.
  • Bug fix: The presence of 3D polylines in a DXF or DWG file could potentially result in the imported image being positioned incorrectly (when using Sketch Pictures).
  • Bug fix: Imported DWG/DXF images are incorrectly scaled when the viewport(s) are not maximized.
  • Bug fix: In some cases exporting to WMF does not work properly.
  • Other changes:

  • Feature: Translated to Brazilian Portuguese.
  • Feature: Display the number of days remaining for a trial license.
  • Feature: In the Solve Manager, right-click in the list of analyses to quickly select all analyses, parent analyses, child analyses, etc.
  • Bug fix: GeoStudio could crash when switching from Define to Results while typing something into the Grid edit box in the status bar.
  • Bug fix: In some cases if a file is saved while a dialog box is displayed (such as KeyIn Materials), GeoStudio could crash.
  • Bug fix: In some cases GeoStudio will fail to add sections for spatial functions or partial factor records to a report.
  • Bug fix: The unit system on the start page when a file is open always displays S.I. even when Imperial units were actually selected in Set Units and Scale.

SLOPE/W

  • Feature: The verification error message when lines overlap has been made more descriptive (includes the point numbers) to make it easier to identify which lines are overlapping.
  • Change: In KeyIn Materials, for the S=f(overburden) material model, the "Minimum Strength" field was moved from the Advanced tab to the Basic tab.
  • Bug fix: In some cases the solver displays the error “Slip surface calculation error … Cohesive Strength has a value of None” when solving analyses using the S=f(overburden) material model, because the minimum strength associated with the material was ignored. This bug was introduced in the May 2012 Release (version 8.0.4).
  • Bug fix: The solver can compute incorrect results when slip surfaces intersect bedrock layers at the ground surface. Intersecting bedrock can truncate the slip surface, but the interslice function was using the original slip surface extents in its calculations. This could result in incorrect results when using the Morgenstern-Price half sine, clipped sine, trapezoidal, or fully specified side functions.
  • Bug fix: In rare cases View Slice Information can display “Phi Angle”, “C (Strength)” and “Anisotropic Strength Mod.” values from a slice other than the one selected. This problem only occurs for the critical slip surfaces (e.g., the optimized slip surface).

TEMP/W

  • Bug fix: In the Johansen (1975) estimation method for thermal conductivity as a function of volumetric water content, the thermal conductivity was being over-estimated at all water contents to prevent the calculation of negative values at low water contents.

VADOSE/W

  • Bug fix: In the Johansen (1975) estimation method for thermal conductivity as a function of volumetric water content, the thermal conductivity was being over-estimated at all water contents to prevent the calculation of negative values at low water contents.

8.16.1.13452

    These additional changes were made in version 8.16.1.13452. We recommend upgrading for everyone whose maintenance covers this release.

All Products

  • Change: The Print Preview image has been improved.
  • Change: If objects are drawn outside the borders of the page in Page Layout, Zoom Objects will now include them.
  • Bug fix: GeoStudio could crash if the mouse was over the status bar when a file was closed.
  • Bug fix: GeoStudio could crash when switching to Page Layout view.
  • Bug fix: In Page Layout view, incorrect time units were shown behind analysis names in the analysis tree accessible from the toolbar.
  • Bug fix: While in Page Layout, exporting to DXF or DWG can take a very long time, as long as several minutes, during which time GeoStudio is unresponsive.
  • Bug fix: When exporting to DXF or DWG, legend text may have a height of zero, making it appear to be missing. This bug was introduced in version 8.16.0.
  • Bug fix: The message on the status bar that is supposed to give instructions about the current mode does not always get updated correctly.
  • Bug fix: Immediately after opening a new file, the Go To command in the status bar is disabled.
  • Bug fix: Occasionally no page is displayed the first time an analysis is displayed in Page Layout.
  • Bug fix: In some cases when a dialog box is displayed, the Undo command can cause GeoStudio to crash.
  • Bug fix: Occasionally when using Split Region, new regions may not have a material association.
  • Bug fix: Values in the Set Grid dialog box are incorrect in Page Layout.
  • Bug fix: Limits were added to zoom and scale values to avoid the potential of crashing GeoStudio from extreme values.
  • Bug fix: Materials on interface lines were displayed too wide at small zoom factors.
  • Bug fix: Some toolbars or docking windows are available in Define when they shouldn't be.

SLOPE/W

  • Bug fix: Materials using the Undrained model were displayed (in View Object Information, reports, or material tables) with an effective cohesion (Cohesion') instead of total cohesion.
  • Bug fix: Occasionally the Slip Surfaces window is not displayed correctly when it is resized.

All Products

  • Change: The material table displayed through Sketch Text - Insert Field is now sorted alphabetically by the material name.
  • Bug fix: When exporting to a DXF or DWG, some elements may not be exported, and in some cases the resulting file may not be valid unless the Sketch Pictures view preference is turned off. This bug was a regression introduced in version 8.16.0.
  • Bug fix: After exporting a file as a previous version (using the File - Export to Previous Version command), some warnings still appear when opening the exported file with an older GeoStudio version. The warnings can be safely ignored--and will go away after the file has been saved again--but should not have appeared in the first place. This bug was a regression introduced in version 8.15.0.
  • Bug fix: When solving a large number of analyses that are deeply nested in the tree view, GeoStudio could appear to hang for a long time and eventually could crash.
  • Bug fix: Ponded water and safety maps may be displayed incorrectly after changing the reference scale.

The error "Unable to generate surface region and regions above it" was displayed. This was a regression introduced in version 8.14. In some cases GeoStudio would crash while attempting to mesh surface regions.

SLOPE/W

  • Feature: SLOPE/W now includes full support for Partial Factor analysis, including limit state design approaches such as Eurocode 7 and British Standard 8006. Read the engineering manual "Stability Modeling with SLOPE/W" for details.
  • Feature: SLOPE/W now includes new slip surface inspection and visualization options. Use the new Draw Slip Surface Color Map command to display slip surfaces, contours, and the safety map using the same color ranges.

  • Feature: Get fisual feedback about slip surfaces while graphically selecting them, including a tooltip showing factor of safety and a graphical representation showing the slip surface center and radius lines.
  • Feature: More control over view preferences in Results view: choose whether to display the current slip surface (includes the slip surface line itself, shading, slices, and factor of safety label); choose whether to display the critical slip surface above all others; and choose whether to display the slip surface definition objects.
  • Feature: Reinforcement in the passive zone is now applied if the resulting reinforcement load is acting in a direction causing the slope to give a higher factor of safety.
  • Feature: Reinforcement properties can now be included in probabilistic and sensitivity analyses.
  • Feature: Newmark analyses now display KMax - the maximum average acceleration from the side of the acceleration record with the largest area above (or below) the yield acceleration. Such analyses may return improved velocity and displacement values in some rare cases.
  • Feature: The Slip Surfaces docking window allows you to choose what to do with the "current" slip surface when you change analyses: either keep the same slip surface number selected, or switch to the critical slip surface of the new analysis.
  • Feature: The Slip Surfaces docking window allows you to type a slip surface number to select it.
  • Feature: The Slip Surfaces docking window is now more responsive when displaying a large number of slip surfaces.
  • Change: Water surcharge now is excluded in the pore-water pressure calculations using B-bar/Ru coefficients
  • Change: Speed improvements were made to Results View for analyses with a large number of slip surfaces.
  • Change: Many SLOPE/W example files have been updated.
  • Bug fix: Under some rare circumstances, the SLOPE/W solver could stop responding (hang).
  • Bug fix: Graphs displayed using Draw Sensitivity or Draw Probability did not update when the current slip surface changed.
  • Bug fix: Graphs displayed using Draw Graph did not update when the current slip surface changed.
  • Bug fix: The default unit weight of water assigned to a tension crack was incorrect when using imperial units.
  • Bug fix: It was not possible to add new Lambda Values when the list of Lambda Values for the Linear Search method was empty.

  • Bug fix: Creating a single grid point does not create an undo/redo item.
  • Bug fix: In some cases for a Monte-Carlo analysis, when Cohesion and Phi are both specified in Set Probabilistic Parameters and a C-Phi correlation coefficient is specified, results may be incorrect.
  • Bug fix: In rare scenarios GeoStudio is unable to read results generated by a sensitivity analysis.
  • Bug fix: Some shallow slip surfaces may not be generated.
  • Bug fix: When editing some of the SLOPE/W lines using the KeyIn commands, the points on the line were not always displayed in sorted order. This bug specifically affected piezometric lines, fully specified slip surfaces, surcharge lines and tension crack lines.
  • Bug fix: View Object Information did not display any information about the axis of rotation.
  • Bug fix: In Draw Graph in a sensitivity analysis, the Run combo box was not displaying properly when multiple modifiers were being used.

SEEP/W

  • Change: The Plan View analysis in SEEP/W ensured that the saturated conductivity of a K-function was used even if the pore-water pressure was negative. Although the restriction is theoretically correct, it prevented an add-in material model from receiving the actual solved pore-water pressure when it was negative. The restriction was removed because the Saturated Only model can be used in place of the Saturated-Unsaturated material model to ensure the saturated conductivity is used in the Plan View analysis.
  • Bug fix: GeoStudio could potentially crash after a flux section was selected.

SIGMA/W

  • Bug fix: In some cases for axisymmetric analyses with a central angle of 360 degrees, the verification error "Neither force nor displacement has been applied in this analysis" would be reported incorrectly.

  • Bug fix: Climate data import did not work. (This was a regression introduced in 8.14.0.)
  • Bug fix: GeoStudio could potentially crash after a flux section was selected.

CTRAN/W

  • Bug fix: GeoStudio could potentially crash after a flux section was selected.

AIR/W

  • Bug fix: GeoStudio could potentially crash after a flux section was selected.

VADOSE/W

  • Bug fix: Climate data import did not work. (This was a regression introduced in 8.14.0.)
  • Bug fix: GeoStudio could potentially crash after a flux section was selected.

8.15.1.11236

    These additional changes were made in version 8.15.1.11236

All Products

  • Bug fix: Upgrading from 8.14 to 8.15 loses all non-English languages.

8.15.2.11331

    These additional changes were made in version 8.15.2.11331

All Products

  • Feature: When typing coordinates in the status bar while in a draw mode, you can now specify a relative point with an angle and an X or Y offset. For example: @x10<30 will move 10 units to the right and up 30 degrees.
  • Change: Minor performance and stability improvements.
  • Change: Improved meshing reliability.
  • Bug fix: Floating regions could not always be selected using Modify Objects. In some cases the domain region below it would be selected instead.
  • Bug fix: Merge Regions may not merge two adjacent regions properly.
  • Bug fix: In Draw Mesh Properties, the mesh is not updated after clicking “Remove Constraints”. You can force the mesh to update by applying other constraints or modifying the geometry. This bug was a regression introduced in version 8.14.
  • Bug fix: In some cases a solver may fail while attempting to reference initial conditions from a steady state analysis, and display an “Invalid time step” error.
  • Bug fix: In some cases GeoStudio may crash while editing initial conditions in KeyIn Analyses.
  • Bug fix: GeoStudio could crash when clicking "Copy" in View Result Information. This bug was a regression introduced in version 8.15.0.
  • Bug fix: In View Result Information, dragging a rectangle could select the wrong gauss points.
  • Bug fix: View Result Information is now faster when selecting a large number of nodes.
  • Bug fix: Some parts of the software always appeared in English, even if the rest was displayed in a different language. This bug was a regression introduced in version 8.15.0.
  • Bug fix: A few issues were fixed related to translations in various languages.
  • Bug fix: A DWG or DXF imported as a Sketch Image would hide any other images behind it. This bug was a regression introduced in version 8.15.0.
  • Bug fix: File Export incorrectly listed AutoCAD DWG files as an option for exporting. Currently the only AutoCAD file type supported for exporting is DXF.
  • Bug fix: In some cases, especially with very small regions, importing regions from DXF may cause GeoStudio to crash.
  • Bug fix: When using licenses tied to multiple USB dongles with 64-bit Windows, GeoStudio was only able to detect one of the USB dongles. This bug was a regression introduced in version 8.15.0. With this new release, all USB dongles will be detected by default, but in order to run GeoStudio from a remote desktop you must go to Help - License Management - Local Settings, and check the "Use 64-bit Licensing" checkbox. Due to a constraint in the underlying licensing software, 64 bit licensing will only detect a single USB dongle at a time.

SLOPE/W

  • Bug fix: Not all probabilistic graphs could be viewed. This bug was a regression introduced in version 8.15.0.
  • Bug fix: Contours were not always updated when changing the time step while in Results View.
  • Bug fix: When exiting the Draw Entry and Exit mode by right-clicking, the mouse cursor would not be reset.
  • Bug fix: In View Slice Information, using the keyboard's arrow keys after a mouse click was not changing the selected slice. This bug was a regression introduced in version 8.15.0.
  • Bug fix: GeoStudio may crash if a SLOPE/W analysis is solved while in the Select Slip Surface mode.
  • Bug fix: In some cases the Slip Surfaces window may not display properly the first time GeoStudio is run, or after using Window - Reset Window Layout. Closing and re-running GeoStudio will normally solve the problem.
  • Bug fix: GeoStudio may crash when viewing results of a sensitivity analysis. This bug was a regression introduced in version 8.15.0.

SIGMA/W

  • Bug fix: In KeyIn Analyses, when getting initial conditions from a parent and that parent is a SIGMA/W Coupled Consolidation analysis, it was not possible to select "(all)" as the time steps.

8.15.3.11339

    These additional changes were made in version 8.15.3.11339

All Products

  • Bug fix: GeoStudio is unable to use Activated licenses on 64-bit Windows. This bug was a regression introduced in version 8.15.2.

8.15.4.11512

    These additional changes were made in version 8.15.4.11512

All Products

    Improved application stability working with the geometry in GeoStudio. Problems fixed with this change include:

  • Bug fix: GeoStudio may incorrectly display the error message "Unable to use results from file. The mesh is incompatible with this file" when attempting to load results from another analysis, even though the other analysis was solved using the same mesh.
  • Bug fix: GeoStudio may crash when modifying region geometry.
  • Bug fix: GeoStudio may crash when saving a file.
  • Bug fix: In some cases, especially with very small regions, importing regions from DXF may cause GeoStudio to crash.
  •  

    These bugs were also fixed:

  • Bug fix: The Student and Basic Editions may incorrectly indicate there are too many regions, and prevent the file from being saved.
  • Bug fix: Combo boxes in a toolbar (such as the Contour combo box) may not accurately indicate what is currently selected.
  • Bug fix: When an analysis was exported to DXF format, legends in the exported drawing appeared as solid white rectangles.
  • Bug fix: Some changes made in Set Units and Scale that affect the mesh (such as changing the Central Angle for an axisymmetric analysis) would not be applied to the mesh until the next time the mesh was regenerated (such as by making a change to the geometry). This bug was a regression introduced in version 8.15.0.
  • Bug fix: In File - Import as Regions, in some cases when importing from DWG/DXF an incorrect scale factor was suggested.
  • Bug fix: Material assignments on a line were not preserved when the line was split.
  • Bug fix: There was a problem with the DWG/DXF importing where in some cases an incorrect scale factor was suggested. This has now been fixed so the suggested scale more accurately represents the contents of the DWG/DXF file.
  • Bug fix: Material assignments on a line were not preserved when the line was split.

SLOPE/W

  • Bug fix: The Slip Surfaces window may display incorrect left and right angles for the optimized slip surface.
  • Bug fix: GeoStudio could crash when switching to Define view while in Select Slip Surface mode.
  • Bug fix: Contour labels on the grid of centers (when contouring factor of safety) were not displayed with the user-defined number of significant digits.

SIGMA/W

  • Bug fix: The starting time and duration may be incorrect for analyses whose type is "SIGMA/W Stress", "QUAKE/W Stress", or "QUAKE/W Newmark Deformation". This bug was a regression introduced in version 8.15.0.
  • Bug fix: GeoStudio crashes when in Results view for a SIGMA/W analysis that has not been solved. This bug was a regression introduced in version 8.14.

QUAKE/W

  • Bug fix: The starting time and duration may be incorrect for analyses whose type is "SIGMA/W Stress", "QUAKE/W Stress", or "QUAKE/W Newmark Deformation". This bug was a regression introduced in version 8.15.0.

8.15.5.11777

    These additional changes were made in version 8.15.5.11777. We recommend upgrading for everyone whose maintenance covers this release.

All Products

  • Bug fix: In some cases GeoStudio would not release unused space at the end of a .Gsz file. This caused .Gsz files to be larger than necessary.
  • Bug fix: After applying a Windows 10 update, activated licenses may no longer function.
  • Bug fix: The Solve Manager may report 'Results out of date' when in fact nothing has changed.
  • Bug fix: When printing, the Fit to Page button did not properly scale the image to a single page.
  • Bug fix: Importing a DXF or DWG as a background sketch image would scale improperly in some occasions and wouldn't overlap the region geometry. This typically occurred when text was present in the DXF or DWG.
  • Bug fix: In some cases GeoStudio could become unresponsive (hang) while importing regions using File - Import Regions.
  • Bug fix: Drawing a region on top of another region can sometimes cause errors in Verify.
  • Bug fix: Split Regions could fail in some valid cases.
  • Bug fix: In some cases where the Structured Grid mesh patterns are used GeoStudio could crash if the mesh is over constrained.
  • Bug fix: Trying to split a region with a mesh type of 'Rectangular grid of Quads' or 'Triangular grid of Quads / triangles' could fail.
  • Bug fix: When an analysis gets initial conditions from a specific time step of its parent, and the parent is changed so it has only a single time step, the child analysis would have an invalid time step selected but the Time combo box would disappear so there was no obvious way to correct the mistake.
  • Bug fix: In Draw Graph, the 'Select Time Steps' field might switch to 'Custom' unexpectedly.
  • Bug fix: In some cases, results did not load correctly when opening files solved by GeoStudio 2007 or earlier.
  • Bug fix: GeoStudio may incorrectly display the error message 'Unable to use results from file. The mesh is incompatible with this file' when attempting to load results from another analysis, even though the other analysis was solved using the same mesh.
  • Bug fix: GeoStudio may crash when saving a file.

8.15.6.13446

    These additional changes were made in version 8.15.6.13446. We recommend upgrading for everyone whose maintenance covers this release.

All Products

  • Bug fix: Importing a DXF or DWG as a background sketch image would scale improperly in some cases. This typically occurred when the imported file included text.
  • Bug fix: The presence of 3D polylines in a DXF or DWG file could potentially result in the imported image being positioned incorrectly (when using Sketch Pictures).
  • Bug fix: Imported DWG/DXF images were incorrectly scaled when the viewport(s) were not maximized.
  • Bug fix: GeoStudio could crash when switching from Define to Results while typing something into the Grid edit box in the status bar.

SLOPE/W

  • Feature: The verification error message when lines overlap has been made more descriptive (includes the point numbers) to make it easier to identify which lines are overlapping.
  • Bug fix: In some cases the solver displays the error “Slip surface calculation error … Cohesive Strength has a value of None” when solving analyses using the S=f(overburden) material model, because the minimum strength associated with the material was ignored. This bug was introduced in the May 2012 Release (version 8.0.4).
  • Bug fix: The solver can compute incorrect results when slip surfaces intersect bedrock layers at the ground surface. Intersecting bedrock can truncate the slip surface, but the interslice function was using the original slip surface extents in its calculations. This could result in incorrect results when using the Morgenstern-Price half sine, clipped sine, trapezoidal, or fully specified side functions.
  • Bug fix: In rare cases View Slice Information can display “Phi Angle”, “C (Strength)” and “Anisotropic Strength Mod.” values from a slice other than the one selected. This problem only occurs for the critical slip surfaces (e.g., the optimized slip surface).
  • Bug fix: In some cases GeoStudio will fail to add sections for spatial functions or partial factor records to a report.

All Products

    Workflow Improvements

  • Feature: Previously any dialog or drawing mode had to be closed before switching to a different analysis. Now many of them can remain open. For example, you can now leave the Draw Graph window open as you change analyses, to compare results across analyses. Similarly you can remain in Draw Material mode as you change analyses, to make changes to materials across many analyses.
  • Feature: Add "Current" time selection to Draw Graph, to graph using the time step selected globally.
  • Feature: The list of time steps in Draw Graph are updated while solving.
  • Feature: An "Apply" button has been added to the Set Units and Scale dialog box to make it easier to test changes to the problem's scale and extents.
  • DXF Improvements

  • Feature: DXF import--via File Import Regions and via Sketch Pictures--is now capable of importing 3D DXF files. When a file's entities are determined to fall on a 3D X-Z plane, they are re-oriented to align with the 2D X-Y GeoStudio plane. The orientation of the 3D DXF plane is determined by calculating the normal vector of the 3D elements. This is currently limited to a single plane in 3D-space.
  • Feature: When importing regions from a DXF file, GeoStudio was limited to importing only polylines whose "closed" property was set to "yes". This functionality has been extended to include polylines whose start and end points meet. In addition, GeoStudio now supports importing closed HATCH elements as regions.
  • Feature: When using Sketch Pictures to import a DXF, GeoStudio now has improved MTEXT handling, including MTEXT with varying formatting, or rotated MTEXT.
  • Feature: TrueType fonts in TEXT and MTEXT styles are retained when importing DXF files using Sketch Pictures.
  • Feature: An "Apply" button when importing DXF files as regions or as sketch pictures allows adjustments to be made while importing.
  • Bug fix: When using Sketch Image to import a DXF file, entities were painted black instead of using the layer color.
  • Performance Improvements

  • Feature: GeoStudio is much more responsive when working with large files that contain many analyses, many time steps, or a large domain mesh. For example, the files will open much faster, the Solver will start running more quickly, GeoStudio is more responsive while solving, and Results view is much more responsive when you switch between analyses.
  • Feature: Improved shell extensions allow Windows Explorer to better handle large .gsz files without becoming unresponsive or crashing.
  • Feature: Overall rendering speed has been increased by 200-400%. GeoStudio should now be more responsive when contouring large meshes.
  • New Languages

  • Feature: GeoStudio has been translated into French. (The online help and the engineering methodology books are still in English; let us know if you would like these translated.)
  • Feature: The Spanish edition has been updated with new translations, including the ability to display reports and object information in Spanish.
  • Other Changes

  • Feature: For users who opt in, GeoStudio will send anonymous feature and usage information to GEO-SLOPE to help improve the software.
  • Change: GeoStudio no longer automatically regenerates its mesh if it was created by a previous version. This change allows GeoStudio to open files created by previous versions faster and makes it easier to compare results with those generated by previous versions.
  • Bug fix: GeoStudio could crash when editing the Y-Intercept field in KeyIn Functions for a function that does not cross the y-axis.
  • Bug fix: When using multiple Custom Locations in Draw Graph, a node selected twice would produce two graph locations.
  • Bug fix: Draw Graph may crash when plotting vs. time, for analyses with time units defined in seconds and large time values (larger than 2e+9 seconds or 75 years).
  • Bug fix: Text near the page boundaries would sometimes be cut off when printing or copying the entire page.
  • Bug fix: GeoStudio could crash in Draw Mesh Properties when changing a region's corner points.
  • Bug fix: GeoStudio could crash during mesh regeneration.
  • Bug fix: After deleting the Template Folder path and exiting, GeoStudio would crash the next time it was run.
  • Bug fix: GeoStudio could crash while accessing files on a network drive that had been disconnected.
  • Bug fix: On a computer with IE11 installed, the list of analyses on the "file information" view overlapped the filename.
  • Bug fix: In some rare cases, results may fail to be written to file without any error messages.

SLOPE/W

  • Feature: SLOPE/W can now use a new “Root Finder” search method to improve the rate of convergence for some types of limit equilibrium stability problems. This method forecasts the required percentage of the inter-slice force function (lambda) based on previous estimates using a non-linear function. The non-linear prediction can sometimes reduce the number of iterations required to find the converged lambda in comparison to the “Linear” search method.
  • Feature: In Draw Graph, the graph of Lambda vs. F of S includes a point indicating the factor of safety returned by the search method.
  • Feature: When using the Linear search method in SLOPE/W, you can now control the Lambda value at which a solution must be obtained. Previously, this value was always 0.2.
  • Feature: Added the option of doing staged undrained strength seismic analysis using a procedure proposed by Duncan, Wright and Wong (1990).
  • Feature: Improved the 3-stage rapid drawdown implementation so that the undrained strengths more closely match published results.
  • Feature: Improved the responsiveness of the Slip Surfaces window.
  • Feature: Free drainage materials can now be modeled in a SLOPE/W staged analysis by setting the R Envelope parameters to equal the material's Cohesion and Phi values.
  • Feature: SLOPE/W now displays more detailed error messages when a slip surface cannot converge to a solution.
  • Change: "Probability Functions" are now more appropriately titled "Probabilistic Offset Functions". This more clearly declares that each 'Probabilistic Offset Function" is not automatically fit to the range of the parameter. Instead, the range of each function should be applicable to the range of the parameter(s) to which it is applied.
  • Bug fix: GeoStudio could crash when performing a probabilistic analysis with spatial variation when no slip slices were generated.
  • Bug fix: GeoStudio could crash in View Slice Information while viewing the results of a SLOPE/W analysis that had a geometrically invalid slip surface.
  • Bug fix: A 992 error FOS could be generated when the X and Y coordinates were large (in the millions).
  • Bug fix: Some FOS error messages were incorrect in the Sensitivity dialog.
  • Bug fix: Some analysis methods, such as Janbu and Bishop, were not showing the correct Applied Lambda in View Slice Information.
  • Bug fix: In some cases (when the number of starting points is low) the "optimized" factor of safety may be larger than the critical slip surface.
  • Bug fix: The Resistance Reduction Factor was not applied in a geosynthetic reinforcement when the Pullout Resistance was calculated from Interface Adhesion and Interface Shear Angle.

SEEP/W

  • Bug fix: When using a unit gradient boundary condition and an anisotropic material, any anisotropy with different Ky/Kx ratios would result in the wrong applied flux at the unit gradient boundary.

SIGMA/W

  • Feature: The units displayed in the column header for an X-Velocity displacement boundary function were incorrect.

QUAKE/W

  • Change: The analysis type "Equivalent Linear with PWP Only" has been removed. Please use "Equivalent Linear Dynamic" instead.
  • Bug fix: The units displayed in the column header for an X-Velocity displacement boundary function were incorrect.

CTRAN/W

  • Bug fix: In a particle tracking analysis, the user-defined Starting Time was ignored, and always assumed to be zero. This could result in an overestimated travel distance if the actual Starting Time was non-zero.
  • Bug fix: The Particle Shading view preference was not working properly.
  • Bug fix: "View Particle Information" could show incorrect values when a different current time is selected.
  • Bug fix: Choosing View Mass Accumulation from the menu would instead go to View Particle Information. This was a regression introduced in version 8.13.0.

VADOSE/W

  • Bug fix: When using a unit gradient boundary condition and an anisotropic material, any anisotropy with different Ky/Kx ratios would result in the wrong applied flux at the unit gradient boundary.

8.14.1.10087

    These additional changes were made in version 8.14.1.10087

All Products

  • Feature: An "Apply" button has been added to the Set Units and Scale dialog box to make it easier to test changes to the problem's scale and extents.
  • Bug fix: GeoStudio fails to correctly delete old files in its temporary file cache. This can generate unexpected behavior while re-solving existing analyses, such as strange contours or a crash when viewing results after re-solving. To work around this problem, close and re-open GeoStudio after solving.
  • Bug fix: File Save As would fail if GeoStudio was unable to write to the original file (such as if the current user did not have permissions or the disk was full).

SLOPE/W

  • Feature: Draw Graph performance was improved for analyses with a large number of slip surfaces.
  • Feature: Further improved the responsiveness of the Slip Surfaces window.
  • Bug fix: An unnecessary error message would be displayed when selecting a slip surface for which no results were available. This was a regression introduced in version 8.14.0.
  • Bug fix: Some unnecessary warnings were logged while saving a file as an older version.

8.14.2.11317

    These additional changes were made in version 8.14.2.11317

All Products

  • Bug fix: In View Result Information, selecting nodes by dragging a rectangle could sometimes be extremely slow.
  • Bug fix: Imported WMF pictures were not displayed properly. (This was a regression introduced in 8.14.0.)
  • Bug fix: With the "Mesh" View Preference turned on, drawing a material on a region which previously did not have a material, the mesh would not be displayed in that region. The problem could be worked around using View - Redraw, manually regenerating the mesh using Draw - Mesh Properties, saving the file, or solving. (This was a regression introduced in 8.14.0.)
  • Bug fix: GeoStudio may crash when opening a file containing non-latin characters on a computer with a different locale setting. (This was a regression introduced in 8.14.0.)

SLOPE/W

  • Bug fix: In some cases for a Monte-Carlo analysis, when Cohesion and Phi are both specified in Set Probabilistic Parameters and a C-Phi correlation coefficient is specified, results may be incorrect.
  • Bug fix: Under some rare circumstances, the SLOPE/W solver could stop responding (hang).
  • Bug fix: GeoStudio could crash when viewing results from a GeoStudio 2007 file. (This was a regression introduced in 8.14.0.)
  • Bug fix: In some cases for a Monte-Carlo analysis, when Cohesion and Phi are both specified in Set Probabilistic Parameters and a C-Phi correlation coefficient is specified, results may be incorrect.

SEEP/W

  • Change: The Plan View analysis in SEEP/W ensured that the saturated conductivity of a K-function was used even if the pore-water pressure was negative. Although the restriction is theoretically correct, it prevented an add-in material model from receiving the actual solved pore-water pressure when it was negative. The restriction was removed because the Saturated Only model can be used in place of the Saturated-Unsaturated material model to ensure the saturated conductivity is used in the Plan View analysis.

TEMP/W

  • Bug fix: GeoStudio may crash when defining a Convective Surface Fluid temperature function. (This was a regression introduced in 8.13.0.)
  • Bug fix: Climate data import did not work. (This was a regression introduced in 8.14.0.)

VADOSE/W

  • Bug fix: GeoStudio may crash when defining a Convective Surface Fluid temperature function. (This was a regression introduced in 8.13.0.)
  • Bug fix: Climate data import did not work. (This was a regression introduced in 8.14.0.)

8.14.3.13430

    These additional changes were made in version 8.14.3.13430

All Products

  • Bug fix: In some cases GeoStudio would not release unused space at the end of a .Gsz file. This caused .Gsz files to be larger than necessary. This was a regression introduced in version 8.14.0.
  • Bug fix: The Solve Manager may report "Results out of date" when in fact nothing has changed.
  • Bug fix: When printing, the Fit to Page button did not properly scale the image to a single page.

SLOPE/W

  • Bug fix: In some cases the solver displays the error “Slip surface calculation error … Cohesive Strength has a value of None” when solving analyses using the S=f(overburden) material model, because the minimum strength associated with the material was ignored. This bug was introduced in the May 2012 Release (version 8.0.4).
  • Bug fix: The solver can compute incorrect results when slip surfaces intersect bedrock layers at the ground surface. Intersecting bedrock can truncate the slip surface, but the interslice function was using the original slip surface extents in its calculations. This could result in incorrect results when using the Morgenstern-Price half sine, clipped sine, trapezoidal, or fully specified side functions.

SIGMA/W

  • Bug fix: GeoStudio crashes when in Results view for a SIGMA/W analysis that has not been solved. This bug was a regression introduced in version 8.14.0.

    Stability and Performance

  • Feature: The solver now runs as a lower priority process, allowing GeoStudio and other applications running on the same computer to be more responsive while solving.
  • Feature: The GeoStudio finite element Parallel Direct Equation Solver is now up to 10% faster.
  • Feature: Improvements were made to the responsiveness of the application, especially while opening files, solving, and saving.
  • Change: To see a full update of each analysis' status in the Solve Manager window, you must now hit the Refresh button. Basic status information such as the last solved time and any verification errors will continue to be updated any time a file is opened or saved; however, testing whether the solution is "out-of-date" can take a long time, so this now only occurs when you click the Refresh button.
  • Bug fix: A number of crashes have been fixed that were reported by users choosing to send error information to Microsoft after a crash.
  • Licensing

  • Feature: GeoStudio now supports activated licenses that can be used over Remote Desktop.
  • Feature: Improved the stability and responsiveness of license management.
  • Change: Basic and Student license restrictions are enforced at the time the file is saved, to prevent accidentally saving a file that can no longer be opened without a full license.
  • Bug fix: While upgrading, setup could incorrectly indicate that some licenses would not work with the new release because their maintenance had expired.
  • Bug fix: In some cases it was not possible to return a license because the server thought the license had already been returned.
  • Bug fix: In some cases a standalone license could end up being installed on a license server, or a server license on a client.
  • Feature: An activated license could be broken when major changes have been made to the computer on which it was activated. GeoStudio will now repair it the next time it is run.
  • DXF

  • Feature: When importing a DXF as a picture using Sketch Pictures, the page origin, scale and extents can be adjusted automatically to fit the DXF entities, in a manner similar to File Import Regions.
  • Change: Importing a DXF (as an image in Sketch Pictures or as regions in File Import Regions) now uses the User Coordinate System (UCS) of the DXF file if one is defined.
  • Bug fix: The Import Regions command for creating regions from DXF files presented incorrect extents values in the Import Regions from DXF Entities dialog box.
  • Full Unicode Support

  • Feature: GeoStudio now fully supports Unicode throughout the product. This means you can use file names in any language. When changing GeoStudio's display language, you therefore are no longer required to change non-Unicode settings on your system. Simply choose a language from the Edit Options dialog and restart GeoStudio.
  • Feature: The default language in GeoStudio is now the selected Windows display language (for example, Chinese). If a Windows display language is unsupported by GeoStudio then the language in GeoStudio will default to English.
  • Images

  • Feature: File Export now allows exporting as GIF, PNG, JPEG, and other image formats.
  • More Changes

  • Feature: GeoStudio can now load Add-Ins that were downloaded through a web browser without first having to "Unblock" the Add-In dll.
  • Feature: A new Window Reset Layout command has been added, which restores the docking window layout to the original default settings.
  • Feature: KeyIn Regions now supports Copy and Paste in the list view.
  • Feature: A warning is displayed when changing global units in Set Units and Scale, as this setting does not actually convert any values.
  • Feature: Quickly create new projects from a template, directly from the Start Page.
  • Feature: The Start Page now includes a link to a "Getting Started" section in the online help.
  • Change: When solving some subset of analyses in a file, the progress bar in the system's taskbar now takes into account the number of analyses being solved.
  • Bug Fixes

  • Bug fix: GeoStudio no longer allows an analysis to be deleted while it is being solved, as that can lead to data corruption.
  • Bug fix: Contour lines, contour shading, isolines, deformation, and vectors could not always be displayed correctly when choosing specific time steps.
  • Bug fix: In the Result Times window, in some cases clicking on an earlier time step would cause all subsequent time steps to disappear from the list.
  • Bug fix: Not all results (such as Safety Maps and Contours) were available in Sketch Text.
  • Bug fix: When creating a new file, GeoStudio's Start Page was displayed instead of the File Properties view.
  • Bug fix: After saving an analysis with exponential time steps, KeyIn Analyses and View Report both show a missing value in Initial Increment Size, unless the default Initial Increment Size value is overridden by a user specified value.
  • Bug fix: GeoStudio may crash when trying to generate an invalid mesh.
  • Bug fix: Starting the solver from the last saved step would overwrite some previously computed results on the domain, such as the number of unconverged nodes and cumulative values.
  • Bug fix: In KeyIn Analyses, line breaks in the Description edit box were lost while saving the file.
  • Bug fix: Changing the Element Thickness or Central Angle in Set Units and Scale failed to re-generate the mesh with the new values. This bug is a regression introduced in the June 2013 Release.

  • Bug fix: GeoStudio could crash when changing a function's type from Add-In Function to any other type of function and back again.
  • Bug fix: When choosing KeyIn Analyses or exiting GeoStudio, other windows may "flicker".
  • Bug fix: In rare cases, cloning an analysis, saving the file, and then re-opening it could display an error about an invalid "CourantNumber"
  • Bug fix: When a file containing legends was exported as an older GeoStudio version and then opened in a previous version of GeoStudio, a warning would be displayed.
  • Bug fix: The Ground Surface Line could be incorrectly generated when there are null regions internal to the domain.
  • Bug fix: GeoStudio could crash generating a mesh when a meshed line cuts at an angle through a surface region.
  • Bug fix: In some cases while resizing a window, other controls in the window will not be displayed properly.
  • Bug fix: GeoStudio could crash when opening a file created by the original GeoStudio 2012 release in cases where the project contains a large number of regions.
  • Bug fix: AddIn functions with fields containing the character sequence "NAN" or "IND" would not be read correctly from file. This could result in failure or wrong answers in analyses using these AddIn functions.

SLOPE/W

  • Feature: Added the ability to adjust the height of a piezometric line during a probability or sensitivity analysis. This feature behaves in a similar manner to GeoStudio 2007.
  • Feature: The reinforcement length and angle are now displayed in the KeyIn Reinforcements dialog box.
  • Bug fix: Slip surfaces obtained from a parent analysis could not be optimized.
  • Bug fix: When using the Strength = f(depth) or Strength = f(datum) functions with a large rate of increase, GeoStudio could display an error message before checking for the min and max values.
  • Bug fix: When using a parent analysis in SLOPE/W to compute a slip surface for the child analysis, there were some cases where an error would be generated in the solver when using the slip surface in the child analysis.
  • Bug fix: In a Monte-Carlo analysis, a regression was introduced in version 8.12 with the use of the C-Phi correlation coefficient. If the "Set Probabilistic Parameters..." dialog was displayed, the correlation data was corrupted and the correlation coefficient was ignored.
  • Bug fix: In a Monte-Carlo analysis, the generalized spline distribution would always fail, causing a verify error.
  • Bug fix: Contours did not update when switching between analyses.
  • Bug fix: For a probabilistic analysis, the units displayed for P(failure) were incorrect in Sketch Text and in the graph of P(failure) vs. Time.
  • Bug fix: Computations of localized FOS in a Newmark Analysis were using dynamic rather than static stresses. This bug affected the local stability factor, but did not affect the overall solution.
  • Bug fix: The "Ignore seismic load in base shear strength computation" option in KeyIn Seismic Load was not working properly. When the option was used, the shear strength at the base of the slice was incorrect and the force polygon was not closed.
  • Bug fix: Slip surfaces may be incorrectly reported as invalid ("air gap") when a steep region line intersects the slip surface.
  • Bug fix: Safety map colors were incorrect: the range of colors did not extend all the way to the End Color.
  • Bug fix: Some results were unavailable for the optimized slip surface.
  • Bug fix: The pore water pressure at the base of a slice may be too large when the material is specified with a BBar and there is a surcharge load or ponded water.
  • Bug fix: In some rare cases the solver could crash because a problem generating slip surface slices.
  • Bug fix: The solver may never complete when a slip surface passes through only air and bedrock materials.
  • Bug fix: The solver could crash when dealing with a large number of slip slices.

SEEP/W

  • Feature: The Draw Graph command now allows filtering the convergence plot (X-Conductivity vs. Matric Suction) by each material.
  • Change: The maximum value for Initial Rate in the hydraulic under relaxation criteria is now enforced as 1.0.
  • Change: The K convergence graph is now based on the actual computed total head of an iteration. In the past, the under-relaxed total head was used. This change better highlights the actual K difference when a solution is not converged.
  • Bug fix: GeoStudio could crash when a flux section contained a node that didn't belong to an element.

SIGMA/W

  • Change: The maximum value for Initial Rate in the hydraulic under relaxation criteria is now enforced as 1.0.
  • Bug fix: When using a function of Y Stress, the Ei and C values were only being updated based on the stresses in the parent analysis; now they are updated at the beginning of each time step.
  • Bug fix: The solver could crash in an Insitu analysis when a boundary function is applied.
  • Bug fix: When an E vs. Y stress function is used, or when a Total C vs. Total Y Stress function is used, the Y stresses are now based on Insitu stresses rather than on the stresses at the current iteration.

QUAKE/W

  • Change: "Insitu Y Total Stress" and "Insitu PWP" are now saved to the .gsz file in the same way as they are by SIGMA/W, so that the insitu stresses computed by QUAKE/W can be used in SIGMA/W for Ei computation when needed.
  • Bug fix: The solver was not computing the Liquefaction flag for Initial Static analyses.
  • Bug fix: The Cohesion Prime and Phi Prime fields in KeyIn Materials were not displayed and could not be changed.
  • Bug fix: Applied boundary forces were computed incorrectly when using stress boundary functions and hydrostatic pressure boundary functions in an equivalent linear dynamic analysis.
  • Bug fix: The G Reduction and Damping Ratio functions did not properly handle estimation parameters in U.S. Customary Units.
  • Bug fix: The solver may crash when an analysis contains higher order elements with structural beams.
  • Bug fix: Axial forces were over-estimated in Equivalent Linear Dynamic analyses.
  • Bug fix: The constant stress option, which resulted in an averaging of stresses within an element, has been removed from the insitu analysis. This option had already been removed from all analysis types within SIGMA/W at the original release of Version 8.

AIR/W

  • Change: The maximum value for Initial Rate in the hydraulic under relaxation criteria is now enforced as 1.0.

VADOSE/W

  • Feature: The Draw Graph command now allows filtering the convergence plot (X-Conductivity vs. Matric Suction) by each material.
  • Change: The maximum value for Initial Rate in the hydraulic under relaxation criteria is now enforced as 1.0.
  • Bug fix: When splitting a surface line of a surface region which has properties such as materials, boundary conditions etc., these properties were not being correctly applied on the newly generated regions after the split.

8.13.1.9253

    These changes were made in version 8.13.1.9253

All Products

  • Bug fix: When displaying a graph with a value of "distance/area", the units may be displayed incorrectly. This bug was a regression introduced in version 8.13.0.
  • Bug fix: Exporting to DXF produced a file that could not be opened by AutoCAD because it contained invalid group codes. This bug was a regression introduced in version 8.13.0.
  • Bug fix: Sketch Pictures showed a dialog to adjust page position and scale after selecting a file. This dialog only applies to importing DXF files and should not be shown for other file types. This bug was a regression introduced in version 8.13.0.
  • Bug fix: On Windows 8.1 systems FLEXIDs would appear mulitple times in the License Management dialog.

VADOSE/W

  • Bug fix: VADOSE/W was unable to solve an analysis with activated regions.

GeoStudio 2012, September 2013 Release

GeoStudio 2012, September 2013 Release (3.9 MB)
version 8.12.4.11377
Requires maintenance through September 2013

Below are the changes made since the previous release.

History

    • version 8.12 - 16 Sep 2013

    • version 8.12.3 - 29 Oct 2013 - This is a minor update to the previous September 2013 Release to fix two specific bugs.

    • version 8.12.4 - September 30, 2015 - minor update to fix a few specific bugs

Highlights

    Here are some of the main areas of focus for this release:

    SLOPE/W - A SLOPE/W analysis can now specify another SLOPE/W analysis as its "parent". This "child" analysis can then obtain its slip surfaces from its parent's saved slip surfaces (the top ten most critical, for example). This feature can be helpful when doing sensitivity or probabilistic analyses in which the analyses can be done only on the saved critical slip surfaces rather than on every slip surface.

    We've continued to improve the speed of the SLOPE/W solver on computers with multiple cores.

    SLOPE/W's factor of safety graphs have been moved into Draw Graph, and we've expanded the number of slice parameters that can be graphed. GeoStudio will automatically add common graphs when you open or create a file.

    The "High Strength" material can now control unit weight in the unsaturated zone.

    Legends - Add legends to your drawing for contours, factor of safety contours, and safety maps.

    Licensing - We put a lot of effort into making licensing work more smoothly with this release. A new wizard steps you through installing any kind of license. When a license is not available, the error message should be helpful, clear, and offer troubleshooting steps.

    To avoid installing a newer version of GeoStudio that is not covered by your license’s maintenance period, Setup will do its best to detect your licenses and warn you about potential license problems before you upgrade. We’ve also updated our web site to more consistently mention what maintenance is required for a specific GeoStudio version.

    Functions - Time-based functions that can be "cycled" were sometimes difficult to use. Now they include a "period" parameter to control how long the cycled period is, and they no longer project "backward" in time.

    Pictures - We've added support for additional common file types, including JPEG, GIF, PNG, and more. Pictures (and other objects) can be resized while maintaining their original proportions by dragging one of the corner handles in Modify Objects.

    Sharing Files Between Versions - Sharing .gsz files with people running earlier versions of GeoStudio? The File Export as Previous Version command now supports saving files in earlier GeoStudio 2012 formats (from before November 2012).

    Sorting - Lists of objects (such as the list of materials in KeyIn Materials) are now sorted by the object's name. You can change sorting by clicking on a column header.

All Products

    Changes related to legends:

  • Feature: Add legends to your drawing for contours, factor of safety contours, and safety map. The tutorial files for each product have also been updated to demonstrate this new feature.
  • Changes related to licensing:

  • Feature: Common licensing-related error messages have been reworded to be more helpful in identifying the problem.
  • Feature: The Test button in the License Manager Network Settings tab is now available in both administrator and non-administrator modes, to test the availability of a license server.
  • Feature: Improved error messages for some common license activation failures. New License Installation wizard to help install licenses.
  • Bug fix: In some cases, GeoStudio could acquire a network license from a server even after the server name was removed from the list of license servers.
