How to set the input power in HFSS from a Circuit co-simulation

Co-simulation allows the circuit model to control excitations for post-processing of the EM solution. To set the input power in HFSS, adjust the ACMAG in the voltage source properties based on the following relationship:

For example, with a 50-ohm load, setting ACMAG to 20V in Circuit achieves 1W of input power.

Once the excitation is set, push back the excitation to HFSS for analysis of the EM solution.
