HFSS15: Assigning Symmetry Boundaries

For Driven Modal or Eigenmode Designs

A symmetry boundary represents a perfect E or perfect H plane of symmetry. Symmetry boundaries enable you to model only part of a structure, which reduces the size or complexity of your design.

To assign a Finite Conductivity boundary:

1. Select a surface on which to assign the boundary and click HFSS>Boundaries>Assign>Symmetry to bring up the Symmetry Boundary dialog box.

2. Select the type of symmetry plane the boundary represents: Perfect E or Perfect H.

3. Click Impedance Multiplier.

If the design includes a port, you must adjust the impedance multiplier or the computed impedances will not be for the full structure.

The Port Impedance Multiplier dialog box appears.

4. Type a value in the Impedance Multiplier box, and then click OK.
