Hello,

I want to perform prestressed harmonic analysis and I have followed one video by @peteroznewman . In that, He performed one-way fsi and I want to do Two-way fsi because fluid also effects on membrane velocity in my case.

I want to simulate a CMUT device( Capacitive micromachined ultrasonic transducer) with considering fluid medium (Water) on it.

We need a full vibroacoustic analysis. The fluid is influencing the vibrations by adding mass to the structure.nnThis post is describing how you can do this.https://forum.ansys.com/discussion/5386/plate-simulation-with-harmonic-acoustics-in-water-domainn

nnThank you so much for your help.nIn all this post, They have submerged plate in fluid medium but I want only one face of structure interact with fluid. It means fluid is present on top of the membrane. Do you have any idea, How to apply fluid on top of the membrane ?nI am following this paper.nhttps://ieeexplore.ieee.org/document/1563262nApart from that, I have to do prestressed analysis. In static analysis, I am applying DC biased volltage using TRANS126 element and EMTGEn command.nI have attached my model also. I did one mistake in that model, I also submerged plate in fluid But I don't want that. Also I am expecting result as FIG.14 in that paper.nnCould you please review it?Thanks and regards,nDhruvinn
