When using shapes to define an FEA mesh, use a Region command to define material properties assigned to each shape.
Scripted Input Files
Once the mesh is ready to use shapes, elements within shapes are assigned to materials by using a series of Region commands. The Region command defines material type, thickness, and angle (needed for some anisotropic materials):
Region (matid),(thick),<(angle)> (any number of shape commands) EndRegion
where
- (matid) is the material ID for a previously defined material.
- (thick) is the thickness of the region in mm.
- (angle) is an optional angle for the material which is only relevant for anisotropic materials. It can be entered as a number or as a user-defined function of the coordinates for the element centroid. The units are degrees.
Between the Region command and the subsequent EndRegion command, there can be any number of Rect, Rect, and PolyPtcommands to define the geometry whose elements will use the region's material properties.
