Take some time and read this older huge thread about this topic :o

It's quite revealing...
mogwai.

HFSS is better,but it requests a very larger memory and takes a lot of times when computing complicated problem.
here just my opinion.

either is enough for common design or simulation .

CST is more simple. And the very important problem for CST and HFSS is right assigning a port .

This thread seems to be flame again 8O
I'm locking this topic.
