The response of a part depends on the material assigned to the part. SimulationXpress must know the elastic properties of the material of the part. You assign material to the part by picking a material from a material library. Materials in SolidWorks have two sets of properties, visual and physical (mechanical). SimulationXpress uses the physical properties of the materials defined in the SolidWorks Material library. Materials can be isotropic, orthotropic, or anisotropic. SimulationXpress supports isotropic materials only.
You can assign a material either before or after starting SimulationXpress.
