Hi

See the course I mentioned and go through as we said all the examples there.

So if you are looking into a frequency based harmonic analysis (so sinusoidal signals - so harmonic acoustic analysis), then use the harmonic acoustic system,

but if it is a general time load and time domain analysis (e.g., transient acoustics so pressure will be a function of time), then we need the coupled field transient to do transient acoustics.

Hope all this helps
