Simulation breaks when adding more than two numeric ports

Please login with a confirmed email address before reporting spam

Hello, I am trying to simulate a straight rectangular waveguide with a half ring very close to it. As long as the simulation has two ports it works fine. But as soon as I attach an 3rd numeric port to see how much light is being coupled in the ring, the siulation gives weird results. Can anyone shed any light on what might be the case ?

I am using the wave optics module for the simulation. (Electromagnetics, Frequency Domain)

My guess is that this is due to an error somewhere in your specification of the many various conditions, solver settings, etc. If you haven't already found those error(s) yourself, then I encourage you to post your model to the forum so that others can take a closer look at it.
