Existing material files can be loaded using the Load Material From File option, or using the option. In either case, a file browser will open for you to select a material file (*.mat). Loaded material files will be listed in the Display tree, under Material Properties.
The following Nastran materials are supported:
MAT1 (Linear isotropic material properties)
MAT2 (Linear anisotropic material properties for two-dimensional elements)
MAT8 (Orthotropic material properties for isoparametric shell elements)
MAT9 (Anisotropic material properties for isoparametric solid elements)
MATS1 (Stress-dependent properties for nonlinear materials)
MATT1 (Temperature-dependent properties for MAT1 entry fields via TABLEMi entries)
MATT2 (Temperature-dependent properties for MAT2 entry fields via TABLEMj entries)
MATT9 (Temperature-dependent properties for MAT9 entry fields via TABLEMk entries)
