Dear all,
I'm new to Comsol sofware.

Could someone please tell me if I can use PML in eigenfrequency analysis mode in piezoelectric devices interface of structural mechanics Module. I'm using Comsol version 4.3a.

Thanks in advance.

Hi

I have used PML in solid mechanics model for eigen frequency analysis. It did work. I guess it should work for piezoelectric as well.

Thank you so much. I tried it and it seemed to be properly work. By the way, could you please share your experience in choosing PML parameters (e.g scale factor,...).

Thanks again.

Hi Ruzbeh,

How do you apply PML in structural mechanics module? I do not see any option for PML.
