Modal acoustic analysis
I want to do some modal acoustic analysis on a silicon membrane as an acoustic region, I would like to consider two cases 1. Water or any fluid 2. Air. I actually tried for that but I am not able to Define FSI Interaction (Shows Question mark). The outer periphery is fixed and already considered as a structural. My aim is to find out resonance frequency and mode shapes.
Thickness of membrane: 1um
Diameter of the membrane : 30um
I don't find any tutorial related to modal acoustic analysis. I have attached my file along with this discussion.
Does someone have experience in Modal acoustic analysis? I have gone through all workshop but I didn't find a solution.
