API methods for plugin function

You use the predefined API methods to define your plugin function. API methods are divided into methods supported by Simcenter 3D and methods supported by the thermal solver.

You use and define these methods differently.

Methods supported by Simcenter 3D are listed under Simcenter 3D method definitions.
Methods supported by the thermal solver are listed under Thermal solver method definitions.

You can find a description of the API methods in the C++ header files located in the [installation_path]\ugstructures\evalplugin\srcfolder. You can find examples of .cpp and .cmd files in the plugin_examples\thermal_solverfolder in the tmg patch.

You can use only the listed methods to write your plugin function.
