HFSS Setup: Solver Tab

Select the Solver tab of the HFSS Setup window to access the following settings.

Port Options (General Mode Only)

• Maximum Delta Zo: Change to Zo specified as a target percentage. The default is 2%.
• Set Triangles for Wave Port: Controls the number of triangles used for a wave port. For designs with lumped ports, this option is not active. Higher numbers of triangles do not benefit a solution setup in this case.
  • Min: Minimum number of triangles on the wave port face.
  • Max: Maximum number of triangles on the wave port face.

Modeling Options

• Enable intra-plane coupling of Pwr/Gnd nets for enhanced accuracy: Check the box to increase accuracy by including interactions between power and ground planes in simulation results.
• Enhanced low frequency accuracy: Check the box to increase simulation accuracy at low frequencies.
