Radiative Heat Transfer Material Model for TEMP/W

Radiative Heat Transfer Model

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.

Requires GeoStudio 2018 R2 or newer.

What Is an Add-In?

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.


Installing this Add-In

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.


Using this Add-In

After installing the Add-In, its functions can be used under Define - Functions in GeoStudio:

  1. From GeoStudio’s Define menu, choose a type of function that this Add-In extends.
  2. Click the Add button to add a new function.
  3. From the “Types” control, select “Add-In Function”.
  4. Click the “Select” button, and select this Add-In from the list.
  5. From the “Functions” control, select one of the functions provided by this Add-In.
  6. Select each “Function Field Name” in turn and type a value.

Understanding Units with Add-Ins

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.
