abc3d problem in HFSS

Hi to all,
I am a newbie in HFSS 9.2. I have designed an inductor which is attached to this message and during the analysis I get the following message:

"[error] Port refinement, process abc3d : There are no tetrahedral faces assigned to boundary "PerfE1". Since boundary operations are order dependent, please check to make certain that this boundary is not being ignored because of other operations on the same surface. It is recommended that you redefine the boundary in question."

I don't know what it exactly means. I found some similar problems in other posts but I couldn't adapt them in my own design.
I d be grateful for any help. Thanks in advance!

Hi
your project cannot be opened in my computer.
can you check it?

Hi....I am a newbie too. And I got the same problem.....Anyone helps?

maybe the port is on the out surface of the model.
or the port is on the pefectE bounday.

Added after 58 minutes:

change material metal4 to copper.

increase the dimentions of the ports.
Regards
