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.&nbsp; My aim is to find out resonance frequency and mode shapes.<\/p>\n<p><\/p>\n<p>Thickness of membrane: 1um<\/p>\n<p><\/p>\n<p>Diameter of the membrane : 30um<\/p>\n<p><\/p>\n<p>I don&#8217;t find any tutorial related to modal acoustic analysis.
