Guidelines for Material Orientation
Be aware of the points discussed here when assigning material orientation.
The two types of material orientation are:
Surface (2D) — Use for shells
Part (3D) — Use for parts, volumes, and solids
Material orientation is associated with an entity, not with a material.
The material directions 1, 2, and 3 defined by the material orientation correspond to the directions listed on the Material Definition dialog box when you enter orthotropic or transversely isotropic material properties.
If you assign a transversely isotropic or an orthotropic material to your model, you must specify the material's orientation or be aware of the default behavior.
If you do not specify material orientation, Creo Simulate assumes the default material orientation.
If you delete an orientation, you set the entity back to its default.
You cannot assign material orientation properties to curves, beams, or 2D shells.
In the FEM mode, you cannot define material orientations that reference cylindrical or spherical coordinate systems.
In the native mode, if you define a material orientation with a cylindrical or spherical coordinate system as a reference, the origin of that coordinate system must not lie on the entity to which you assign the material orientation.
Material orientation is defined in 3D for both 2D and 3D model types.
If you assign a material orientation to a part and that part gets compressed to a surface, the definition of the material orientation changes from one defined over a part to one defined over a surface. The material orientation applies to all the surfaces that Creo Simulate creates when it compresses the part.
You can define any number of material orientations for a model without assigning them.
