Port refinement error - plz help me

Hi all,

I am a new member of this group and a freshman learning HFSS.

I am trying to simulate the microstrip structure on silicon substrate and I get a port refinement error message stating the process abc3d failed unexpectedly.
Please help me solve this error and also let me know what is meant by abc3d and port refinement error.

I am not able to post my file with hfss extension :( so wat should I do?

Thanks,
Pradheesh
