question about the multiport radiation pattern in HFSS

a simple question about the radiation calculation in HFSS.

If the antenna we designed has 2 or more ports, with various feeding amplitude and phase combinations, how can we guide the HFSS to calculate the radiation pattern.

I am using the driven terminal solution types.

Thanks.

You probably want to fool with "edit sources" in the "field overlay" menu. You can turn on multiple ports and specify the relative amplitude and phase of each.

Thanks,Azulykit.

So do you means that whenever I want to change the sources amplitude or phase, I need to re-simulate again?
