I want make a model of acoustic-solid interaction (an acoustic wave made by vibrating solid). But because of time consumption, i don't need structure analysis and it's better to model solid as a rigid body how can i do that in comsol?

If you use the Structural Mechanics module of Comsol, in the Solid Mechanics node you can choose Material Models -> Rigid Domain.
Hi three, there is a case about the Acoustic-Structure Interaction. You can find it on the official website of Comsol. I attached a PDF for you.
