Symmetry Boundaries

In HFSS, symmetry boundaries represent perfect E or perfect H planes of symmetry. Symmetry boundaries enable you to model only part of a structure, which reduces the size or complexity of your design, thereby shortening the solution time.

When you are defining a symmetry plane, keep the following requirements in mind:

• A plane of symmetry must be exposed to the background.
• A plane of symmetry must not cut through an object drawn in the 3D Modeler window.
• A plane of symmetry must be defined on a planar surface.
• Only three orthogonal symmetry planes can be defined in a problem.
