HFSS15: Use Radiation Boundary on Ports

If the design includes waveports, the Use Radiation Boundary on Ports option is enabled under the Advanced options tab of the Solution Setup dialog box.

• If you select this setting, edges which are assigned to ABC and touch a port have an radiation boundary condition applied during the port solution.

• If you do not select the setting, a perfect conducting boundary condition is used during the port calculations.

In most cases this setting has a limited effect on the overall fields or post processed quantities.
