connector simulation model

For a single connector simulation using HFSS, please direct me if you have any comments on it:

Please kindly download my file and check any part of it has error!


1. For a practical case, do I need to setup a definite thickness of the outer shield cylinder with finite conductivity?

2. Do i need to setup a box for boundary? since this is a shielded transmission line, so i didn't have to do so, am i right?

If my file has many errors, please kindly redraw a simple connector model for me to follow your instructions.

THANKS.
