[COMSOL_Users] Fluid- Piezoelectric material

[n***@ymail.com]

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.

Is there a way I can attach my model here.

Thanks!
