Piezoelectric material

Please login with a confirmed email address before reporting spam

Hi,
I have been trying to obtain steady state solution for flow patterns in a microchannel when the fluid is excited by the displacement of piezoelectric material. The issue is that I get non-zero displacement on piezo, but zero velocity. What's even more baffling is that I get non-zero acceleration. This does not make any sense to me. Even when I solve only piezo material, I get non-zero displacement anf acceleration but zero velocity

I have attached my model.

Thanks!
Regards
Nitesh
