Merrick,
I've been in the same situation to evaluate HFSS and CST for connector
design. Both will do the job but there are differences in principle.
HFSS delivers primary data like a VNA will do - CST offers TDR-like data.
Both can convert their data into the other domain.
HFSS does a very adaptive triangular meshing - CST mesh is rectangular.
With HFSS there is a chance to miss something interesting stepping through
frequencies.
CST may have a problem with high-Q situations: you have to wait until all of
the input pulses energy returns. (Not really a problem with connectors.)
Poor meshing gives bad results with both of them. For me it's easier to
indentify meshing problems in CSTs reflection results.
HFSS can deal with frequency dependend material properties more easyly than
CST.
There are differences with dielectric and conductive surfaces too.
My 2 cents.
Thomas
