Hello,

I use to have COMSOL 3.5a and was able to follow the FBAR tutorial to get the expected frequency response. But when I try to do the same in COMSOL version 4.0 and newer, I can't seem to get anything other than the capcitive response. I've also tried many other things, including adding additional physics modules, but that did not help. I've attached my COMSOL file and I'm hoping someone can help me determine what I have done wrong or am missing.

Thanks!

Hi,

I found out that there was a tutorial on something similar when version 4.2 came out. Thanks for your response.

Although I haven't tried it yet just because I'm too busy at the moment, I saw that this one would be of great help:
