A powerful suite of integrated software products for geotechnical modeling & analysis.

Licensing Options

When purchasing GeoStudio software, you must consider what form of licensing will best fit your needs.


Standalone or Network

GEOSLOPE software products are sold as "concurrent use" licenses. The software can be installed on an unlimited number of computers in your office. The number of simultaneous users of the software is restricted by the number of licenses purchased.

A standalone license is installed on an individual desktop or laptop computer, whereas a network license is installed on a computer chosen as the network license server computer, and is thus accessible by all computers on the network.

If a standalone license (also known as a node-locked license) is purchased, the license will require activation. Without activation, the license will not be enabled and the software will not be fully functional. If a license is being shared among several colleagues in an office, the license can be "returned" (deactivated) from one computer and activated on another.  When a "return" is used, it cannot be used again for 30 days.  Each license comes with 10 "returns".  If you are unable to initiate the "return" yourself, you will require assistance from GEOSLOPE technical support.  Access to technical support requires valid software maintenance.

A network license (also known as a floating license) is an ideal solution for offices that share software over a Local Area Network (LAN) or Wide Area Network (WAN). There is no limit to the number of network licenses that can be purchased; the number can be customized to fit the number of users in your company. For example, purchasing one network license allows one person at a time to run the software from any computer on the network; if five network licenses are purchased, a 5-user license will be issued, enabling up to five people to run the software at any given time.

A network license requires activation on a ‘server computer’ which runs a license server program that monitors the number of users concurrently running the GEOSLOPE software. Utilizing a well-known network license management program called ‘FlexNet™ Publisher’, a software license can be granted to anyone on the network if a license is available.

Network licenses can be ‘detached’, allowing an end-user to check out a license and then disconnect from the corporate network. A detachable license offers flexibility, but may not be suitable for all environments. If you wish to utilize this feature, please contact GEOSLOPE for details.

It is possible to change your license type from standalone to network or vice versa, at any time, though costs may be incurred. Please contact GEOSLOPE for details.

Perpetual or Subscription

A perpetual license entitles you to use the software indefinitely. The license itself typically expires every year, but is renewed automatically and at no additional cost to you.

All of our full-feature products can be leased for one-month or one-year terms. At the end of the subscription period, the license expires and the software will no longer function. The license can be renewed for another term.

Subscription licenses are secured by activation. Annual Maintenance is included in the price of a subscription license. 

Individual or Bundled

All GeoStudio software products can be purchased individually. These are known as individual product licenses. Our product names are SLOPE/W, SEEP/W, SIGMA/W, QUAKE/W, TEMP/W, CTRAN/W, and AIR/W.

Licensing products individually allows the licenses to be combined or distributed as needed. For example:

A SLOPE/W license enables a single user to utilize the SLOPE/W software at any given time.
If a SLOPE/W license and a SEEP/W license are purchased, one individual (user) can make use of both licenses on the same computer, or one user can utilize the SLOPE/W license on one computer while another works with the SEEP/W license on a different computer.
If two SLOPE/W licenses are purchased, two users can run the software simultaneously, one with each license. The number of simultaneous users is limited by the number of licenses purchased.
In addition to individual product licenses, GEOSLOPE offers a number of bundled product licenses. These license are also single-user licenses, but enable a user to access more than one product.

If a bundled license is purchased, a single user can utilize the license to work with one, two, or all of the products on that license. Bundled licenses are thus ideal for integrated analyses.

The bundled license names are as follows: GeoStudio Standard, GeoStudio Professional, and GeoStudio Universal. (The GeoStudio Basic Edition license is also a bundled license, but will be addressed in the next, ‘Limited Feature,’ section.)

The Standard license includes SLOPE/W, SEEP/W and SIGMA/W.
The Vadose license includes SEEP/W, TEMP/W and CTRAN/W.
The Professional license includes SLOPE/W, SEEP/W, SIGMA/W, QUAKE/W, and TEMP/W.
The Universal license includes all seven products: SLOPE/W, SEEP/W, SIGMA/W, QUAKE/W, TEMP/W, CTRAN/W, and AIR/W.
Here is an example of how a bundled license works:

A Standard license enables a single user, on one computer, to use SLOPE/W, SEEP/W and/or SIGMA/W. If a second user wishes to work with one of the products, s/he must wait until the license is no longer in use.
If two Standard licenses are purchased, then one user can use any combination of SLOPE/W, SEEP/W and/or SIGMA/W on one computer and thus consume only one of those licenses, while a second user on another computer can likewise use any combination of those three programs and consume the second Standard license.
NOTE: Bundled licenses are considered to be specific products, each with a unique name, and each incorporating different individual products, exactly as listed above. GEOSLOPE offers only these three bundled licenses; it is not possible to substitute products within a bundle or to customize your own license bundle.

Other important details to note regarding GEOSLOPE software products:

Individual product licenses can be upgraded to bundled licenses at any time, though costs will be incurred. Bundled licenses cannot be changed into individual product licenses.
A specific software product cannot be exchanged for another product. It is also not possible to upgrade one product into another product.
Full Feature or Limited Feature

The invidual licenses and bundled licenses mentioned above are full feature licenses, in that they allow you to use every feature in the GeoStudio products. We also offer several limited feature licenses, which have certain restrictions.

Basic Edition

GeoStudio Basic Edition is a limited feature bundled license available for a fraction of the cost of full feature licenses. When using a Basic license, the GeoStudio software restricts the use of certain features and enforces certain limits. To assess whether the Basic Edition is suitable for the types of analysis you are planning to do, please carefully review the "GeoStudio Product Details", which provides point by point feature comparisons between the Basic and full feature licenses, to determine whether the limited feature product will satisfy your modeling requirements.

The Basic Edition is only available as a standalone license, but can be upgraded at any time to a full feature license for an additional fee.

Student Edition

GeoStudio Student Edition is a limited feature bundled license that is available for free. This license is included with the software, and enables you to learn how to do simple geotechnical analyses. To use it, set the License Mode on the GeoStudio Start Page to "Student license". The Student Edition is not licensed for engineering consulting use.

Viewer License

This license is automatically installed with the software to enable any individual to open and view (but not save or solve) a previously analyzed problem. It is useful for someone who wishes to view a completed analysis but has not purchased a license.
