Hello, I am facing one problem in simulation.
I get this error message every time.
"[error] Port refinement, process abc3d : Port "WavePort2" is incorrectly set up. A port must have a non-existent material on one side. Both "Box1" and "cover2" exist. "
What is the meaning of this?
Cover 2 is teflon of coaxial abale, & box1 is air box surrounding structure(horn)
Please find the images attached.
( Basically I am trying to simulate Horn).
