Does anyone know if Comsol can do frequency domian analysis In fluid-structure interaction?

It seems when I do a statioanry analysis, I get sth, but when I set the study step to "frequency domain", everything is zero in my solution.

Thank you in advance!

I was wondering the same thing. I think you just have to do a transient analysis and then take FFT's to get to the frequency domain. MATLAB will help you with this.

Cheers.

This is a good question. I find the same issue coming up in version 4.2, only getting NaN instead of a solution.
