How to Define Open Region for Antenna Simulation in HFSS

[@commonwombat-h6r]

great video, thank you so much!

Thanks. Project manager> model> create open region.

[@i_will_do_it]

does it works for HFSS 15 ?

Thanks...for wideband for example 1 to 10 GHz and my solution frequency is 2.4 GHz. On what frequency I will set the auto open region.

Is "Auto-Open Region" valid to use for transient solver? We are working on a design where the excitation signal has spectral content from 0 to 10 MHz. Since our excitation signal has DC components due to such low frequencies in its spectrum, what would be an appropriate size for the open region to get accurate magnetic fields induced by our model. I couldn't find any hints in the manual under HFSS transient solver about this particular problem we are facing.
