Extend GeoStudio using Add-Ins provided by the GeoStudio community.

GeoStudio Add-Ins can be used in place of any internal GeoStudio function (such as those under the Define menu) or SIGMA/W material model.

The Add-Ins below are ready to use—just install them and restart GeoStudio—but you can also write your own using the Add-In SDK.

This Add-In implements the Darcy-Forchheimer equation for modeling flow at large velocities, when both viscous and inertial effects are present. It is ideal for modeling water flow in coarse-grained soils.

This Add-In implements Hamaker’s extension of the Schuster–Schwarzschild approximation for modeling radiative heat transfer in soils. It is ideal for modeling heat transfers in dry, coarse-grained, soils at ambient temperatures.

This Add-In simulates gas consumption due to mineral oxidation (CTRAN/W) and the heat generation (TEMP/W) caused by the associated exothermic reaction.  It is ideal for modeling the oxidation of sulfidic materials in mine wastes that lead to acid mine drainage.

This Add-In allows the shear strength of a material to be defined using up to three shear normal functions, which is ideal for modeling stress-dependent strength variability common in fractured/jointed rock or stratified soil.

This simple Add-In allows different tau-sigma ratios to be defined for the saturated and unsaturated zones.

This Add-In implements the hypoplastic clay material model developed by Mašín (2012), which can be modified to predict small strain behaviour or to consider the behaviour of clays with meta-stable structure.

The hypoplastic sand material model developed by Wolffersdorff (1996) and implemented by David Mašín at Charles University in Prague captures the pressure- and density-dependent response of both loose and dense sand for a wide range of stress conditions.
