Modelling a coax-fed rectangular waveguide in HFSS v9.0

I have tried to model a coaxial fed rectangular waveguide with HFSS v9 and I think it didn't work. My problem is, basically, that I don't know if I have correcttly drawn the structure. I would appreciate very much if someone sends me by e-mail a tutorial on this matter. I don't have enough points to download a tutorial I found in the forum. My e-mail is: aasanblas@umh.es

Thank you all!
