Two microstrip lines are placed in parallel. Port 1 and Port 2 are on the same face.
Create a face which includes ports, and set the "port" there.
This face doesn't need to have either the material name or the body attribute name, as the purpose of it is only to create the ports.
Electric wall surrounds the model. The boundaries of Port1 and Port2 are treated as electric wall too.
