How to simulate the vibration of a suspended diaphragm, cause by and acoustic wave?

      Hello,

      I'm new to Ansys, and I'm trying to figure out how to simulate the vibration response of a polymer diaphragm to an incident acoustic wave, in water medium. In other words, I need structural and acoustic simulations to be coupled to each other. Eventually, I'm looking for obtaining the frequency response of the diaphragm, to see what its bandwidth is and how much bending/deflection occurs in the diaphragm caused by the acoustic pressure from the acoustic source (a point source).

      I have installed Ansys, and using academic license through school. There is a long list of options, as shown in the screenshot below, and I'm not sure which one(s) to choose for modeling of such structure.

      Please let me know of your opinion.

      Thanks.

      THis video shows how this can be done (use harmonic acoustics with incident plane wave excitation)nnHope this helpsnnErik Kostsonn
