The .dat file was generated from an S-parameter sweep, so it should be formatted correctly. I'm checking and there's data for each port and mode as expected. The data in the file also matches the data I saw in the vizualizer in FDTD.
I can't upload the file for CUI reasons, but can you upload the .dat file that you're using? So I can compare what's different?
