I was first trying to use "Port in Duct" definitions for the inlet and the outlet, then i came across another post and example that used a surface velocity specification so i used that method and i now get results for the Transmission Loss graph, but i still get the error when i try to do a plot of sound pressure level or a far-field mic result.

I have no idea which method would be the best suited... surface velocity or Port in Duct. There doesnt seem to be much documentation or tutorials on how to set up and run acoustics. Any resources anyone can recommend would be very much appreciated!
