Need help in HFSS simulation of ridged wave guide

Hi friends,
Does any one know how to simulate dual ridged waveguide in HFSS?
how to excite?
I am facing some errors.
Please help me out

This is how I would excite it. Best of luck!

Hi Micky74
Have you tried ridged waveguide simulation before?

Well, I have my own analytical software and only use HFSS as a verification tool. HFSS should do fine.

You mean you have written your own analysis software?
thats great.

Has anybody tried quadridged wave guide simulation?
