Some insight on Edge Port issue with dielectric medium

So I'm getting an error that says that I am not allowed to create an edge port on a dielectric medium, but it is clearly on a PEC.

Does anyone have an idea on what I am missing?

Also if this is the wrong place to ask this sort of thing feel free to delete it.

TIA.

Sorry, the error message is not clearly stating what the problem is:

MoM/MLFMM does not support port definitions that defined on PEC/metal strips that lie on a dielectric SEP region.

You have a couple of choices:

set the solution for the dielectric region to VEP
remove a small section of dielectric in the vicinity of the ports
define the ports such that they are embedded inside the dielectric - you can imprint a new edge on the metal rods and define the edge port at that location
use FDTD as the solver

Have a look at the following post:

Thanks JIF, the post you suggested helped.
