Other Material Properties Reference
In addition to the specific properties included with the Material Library, the other material databases also contain predefined variables for various material properties that can be used when creating a model.
The material properties for the predefined materials are accessible from most physics interfaces. Using this information, either create a material property group or define a completely new material.
In the Basic>Property Group window, you can add Output Properties under the Quantities subsection. You can also add Model Inputs to, for example, create a temperature-dependent material property.
