Dear
I am simulating a thin plate (membrane) in COMSOL Multiphysics > Solid Mechanics Module. When I apply periodicity on membrane, the dispersion curve shows straight lines which indicates, periodic condition is not working.
I don't know why, if anyone can comment on this.
Thank you
Dear Roman Anudriev,
Thank you for your response. I will cross check my parameters.
Regards,
Hope the below blog will help you and you can get instructive hints from the example, even though you apply the periodic boundary condition on a membrane.

Hi -- Muhammad and Roman Anufriev , I just started a research on metamaterials, I'm at the stage where I'm trying to figure out how to apply floquet-bloch's boundary condition for periodic waves on Comsol. I've never done that before. Please, can you guys help. I'll really be grateful. Thanks
