problem working with hfss

hi

i m getting 2 errors working with HFSS
kindly help.
1) port refinement, process error. too few conductors were found on port 1. there should be one conductor for each terminal with one additional reference conductor. unintentional contact between conductors may cause this error.
2) simulation completed with execution error on server.

and finally i m getting blank results without any traces.

please suggest what could be the problem associated with it.

Hi,

1) make sure the rectangle is drawn properly (assuming you're using driven terminal lumped port) and check the material assignment for the reference ground
2) not sure what execution error is it. I once had it and it was because i did not have enough hard disk space. you can check into this area.
