I designed an antenna in HFSS and simulated Specific Absorption Rate (SAR). Now, I would like to add 2 conductors into my design as shown in the picture, one carrying (+) and the other (-) of 100 DC Volts, and see the effect of this DC voltage on SAR simulation. Is it possible to do that in HFSS?
You can do it in hfss circuit using the dynamic link. Simulate your antenna and import the results into the circuit, apply whatever voltage you want, run the simulation again, you both circuit and hfss results will be dynamically interlinked.
