Geometry abstraction and polygon geometry

Video: Clean up a midsurface in preparation for meshing

The Polygon Geometry group contains a set of commands that let you perform geometry abstraction operations on your model. Geometry abstraction lets you eliminate issues with the CAD geometry that can cause undesirable results when you mesh your model.

For example, you can use geometry abstraction tools to:

  • Improve the quality of your mesh by manually eliminating problematic geometry.

  • Create boundaries on which to define loads and constraints.

When you first create a FEM file, the software automatically creates “polygon” geometry from the master part. See Polygon geometry for more information.
