Wave Port Termination in HFSS

I am simulating a four port waveguide network in HFSS. If I need to see the field distribution animation when one of the two input wave ports alone is excited. How do I terminate the unused 2nd input port in that case? I am using a driven modal approach

Hi arve9066,

You can set the waveport excitation levels under HFSS->Fields->Edit Sources. The ports automatically "terminate" the structure, so long as the incident mode is solved on the port.
