How to design circular and rectangular WaveGuide by HFSS.

Dear,
I'm a beginner in HFSS ansoft.
I want to design rectangular and circular waveguides, Please let me know how to assign different modes eg TE10, HE01 etc
And how can i display electric and magnetic fields together on waveguide ?

And what should be the length for fundamental modes in both Rectangular and circular waveguide ?

I'll be thankful.

Regards

Why bother? The equations for this are well known. The rectangular case has sine/cosine functions, the circular case has Bessel functions. But these are well known. So I'm puzzled why you want to use HFSS to design a waveguide.

Actually i was instructed by prof. to use HFSS to reproduce the Waveguides (Colorful and nice diagrams) for the new students.
And besides this, I suppose, waveguides can be designed on HFSS. !

Hi zuhaib.aleys
These are the tutorials, I referred to get idea about different modes in rectangular waveguide. (ofcourse got from www.google.com )
