Thanks a lot for your reply, comments and suggestions. I understand it is not an easy task, especially to couple the harmonic response with CFD and that it will take a lot of computing resources... I was thinking just out of the top of my head, what if I just draw a volume surrounding the rotor...

I saw your comments for the question about the cantilever beam, in which someone was trying to obtain the eigenfrequencies of the cantilever, as i understand these eigenfrequencies and eigenmodes oof the cantilever in vacuum right? i want to do exactly the same thing (which i already did) but...

No one? please I am really in trouble over here... I really need to know how to perform the eigenfrequency analysis in air. because if I perform the normal eigenfrequency analysis in comsol it would be like in vacuum... i need the surrounding atmosphere to be air... PLEASE HELP!

I was wondering how would you solve this problem (Eigenfrequency Analysis) if you were to include ''air damping'' any user of COMSOL has any idea? because i kinda have the same problem. i want to include air damping in my eigenfrequency analysis...

I am not sure of what exactly you were talking about either. But yes i want to take into account the effects of air damping while performing the eigenfrequency analysis... Anyone??

Ok maybe I should formulate the question all over again. It doesn't matter what kind of device it is, in my case it is a micro-rotor but it can be a cantilever or anything. The question is how to set up the AIR around the device while performing an Eigenfrequency analysis using COMSOL...

Hello Everyone, I'm new with comsol and would appreciate some help from anyone willing to help me out. Ok so here's my question, I'm trying to perform an Eigenfrequency Analysis for an electrostatic micro-rotor. The problem is I want to take in consideration the effects of the surrounding...
