How to Install and Use an Add-In
This Add-In provides the following functions:
Van Genuchten Constrained Hydraulic Conductivity Function Non-Darcy
Van Genuchten Constrained Water Content Function
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.
Some Add-Ins are distributed ready-to-use on the geoslope.com web site or from third parties, but you can also write your own using the Add-In SDK.
Click “Install Add-In” above to download a self-extracting zip file containing the Add-In. The Add-In will be installed in the Add-In folder. By default the Add-In folder is %APPDATA%\GEO-SLOPE\AddIn, but it can be changed in GeoStudio under Edit - Options.
To uninstall the Add-In, simply delete the .dll from the Add-In folder.
After installing the Add-In, its functions can be used under Define - Functions in GeoStudio:
To figure out what units to use when entering values, first determine if your file's Units of Computation are U.S. Customary or SI (see Define - Project Properties - Settings), then use the units indicated in the appropriate column.
