agilent-hfss

Hi,
Can anyone provide me ith Agilent's HFSS tutorial. I guess this product is no longer supported. I wanted to define a waveguide feed for designing an antenna but cannot get hold of any useful material.
Thanks
Hitesh

agilent provide the new 3D EM simulator, EMDS2006c.

Hi,
Is this compatible with Agilent HFSS? Moreover I needed some material as to how we can define a waveguide feed for this antenna?
