Frustration with CPW wave port HFSS Help

[edit] I am using HFSS

I believe I've made my wave port correctly based on previous answered post, yet I keep getting the error message "p1 is assigned to an internal face". I understand that it thinks my port is "inside" my design, but I'm confused if it really is.

For my antenna design, I ran the traces for 5 GCPW lines to the exact ends of my substrate. Then I placed my wave port normal to these edge coordinates. Therefore, these edge coordinates describe the end of the substrate, the end of the conductors, and the location of the sheet for the wave port. But when I run the simulation I get the "p1 is assigned to an internal face". After I got rid of 4 of my wave ports to inspect just one, and I got the same message.

I tried using lumped ports, but the software (me) get confused on the multiple conductors, and I really rather use the wave port instead of lumps. I hope I explained this ok. THanks.

Any ideas?

Hi again,

I understand that MANY people read my post but found the way I framed my question not easily advisable. Apologies for that and I certainly will improve upon that in the future

I figured out my problem and I was able to simulate the network... although my results are very inncorect, I am grateful to now HAVE results. THanks.

hi i suggested to u at first for question give and picture
i think for CPW structure is better using a lump port and a small U shape thin conductor with connection to both ground
