Work with Physical Assets
Each material should have physical properties (for example density, bend, and electrical resistivity values), which are needed for structural and energy analysis. To work with these parameters, use asset helper classes. For more details about physical asset classes, see Overview of Materials.
For more details about getting and setting these assets from the material element, see Specific Properties of Materials.
