• During Material Assignment, if you select an isotropic material with Material Orientation, Creo Simulate displays a warning and ignores the material orientation property during the run.

• During material assignment, if you select a non-isotropic material but do not specify material orientation, Creo Simulate displays a warning and orients the material along the WCS of the referenced model during the run.

• If you assign materials in assembly mode, the material assignment in the assembly mode takes precedence over the material assignment in the part mode.

• If you do not specify a material when you create beams, shells, and spot welds in part mode, Creo Simulate assigns the material that is assigned to the part, to these simulation entities by default. Furthermore, if the part is not assigned with any material, Creo Simulate displays an error.

• The material assigned at the higher level of assembly overrides the material assigned at the part or subassembly level.

• For volumetric material assignment, Creo Simulate processes the materials in the reverse order of creation of material assignment. That is, the new material assignments take precedence over the older material assignments.

• In an assembly, if you have material assignment in the same level, Creo Simulate processes the materials from the lower level component to the higher level component.

• When you assign a hyperelastic material to a model or any part of the model, you can run either a large-deformation static structural analysis (LDA) or any type of small strain analysis. While running a small strain analysis for models with hyperelastic materials, Creo Simulate uses the small strain properties of the materials.
