I find it hard to find tutorials on ansys acoustic systems. I need to run modal analysis and harmonic analysis to get frequency response(pressure) on a body with FSI that is excited sinusoidally. I keep running into issues when acoustic body(air) is introduced in modal(Acoustic modal) as sans that(modal) it seems to work but runs to a dead end when connected to harmonic. Or is it fine if I neglect the air contained in the structure?Any help would be greatly appreciated. I have attached the structure i have and its internal geometry.
I am using Ansys 19.1 student version and have the acoustic extension
