What is the meaning of "solution frequency" in HFSS analysis setup?

Hi,

I am learning HFSS simulation. I don't understand the meaning of "solution frequency" in analysis setup. How to setup it?

I am trying to simulate a parallel plate waveguide, which has TM1 cut off frequency at 2GHz. If I want to see TM1 mode, I need to setup this solution frequency higher than 2GHz. Am I right?

Thanks in advance.

Hello

The Minimum value for adaptive mesh frequency is 2/3rd of the final frequency required.although you can have it set up for final frequency

When analyzing modes the cut off frequency should be kept in mind,i would say you set up a solution frequency of 3GHz to get proper results.
