FEA Region and Hole Commands

When using shapes to define an FEA mesh, use Region command to define material properties for elements and use Hole commands to remove elements from the mesh.
Region Commands
Once the mesh is ready to use shapes, elements within shapes are assigned to materials by using a series of Region commands (or <Body commands in XML files). In scripted files, the Region command defines material type, thickness, and angle (needed for some anisotropic materials):
Region (matid),(thick),<(angle)> (any number of shape commands) EndRegion
In XML files, the <Body> block is:
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.
