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.
In this video that fork is inside the enclosure but I want fluid on top of the one surface.
so I am not able to define enclosure on it. So I designed a box using Design modeller. When I imported a load of the membrane from the harmonic response in harmonic acoustic I got this kind of error:
*** ERROR *** CP = 4.859 TIME= 12:22:12
The velocities are not defined on the exterior surface of the model in harmonic analysis. Please check the velocity body load carefully.
Here I have attached workbench file. Could anyone please help me?
Thanks and regards,
