I am trying to get a rather simple simulation working so that I can use it in a more complex case, but I am running into problems with computing S-parameters between multiple modes on a port. So the setup is as follows: circular PEC waveguide with ports on each end. Each port is set to numerical which are solved using the boundary mode analysis with two modes being set. I can compute the study step for the boundary mode analysis and I observe two separate modes at each port.
Now I want to use these two solved for modes in a frequency domain study, in which scattering parameters between each port and each mode will be computed. For example, getting S_{21} between mode 1 on port 1 and mode 2 on port 2. I can get it working for a single mode on each port, but I have no clue to get it for multiple modes. Can anyone lend me a hand?

I got to say, a forum mod could of read this post and replied with this answer right away. I question the uselessness of this community sometimes.
