Solved!
My Coordinate System was not properly set...
In my case, I should select Material XZ-Plane System under my Piezoelectric Material Model...

Hey
I'm a newb to comsol too. Just started working on exactly the same problem as mentioned by you, faced the same problem too- no deflection when the potential is applied. But i am not able to solve it. Please elaborate the procedure.
Please help.

It can be for several reasons, as Ricardo said, by a bad definition of the polarization of ceramics, or if you are using the structural module in combination with piezoelectric may not be the coupled correctly configured. When I do a model that combines structural elements and piezoelectric elements its better use the piezoelectric module and define piezoelectric materials and linear elastic on the same module, for this way structural coupling is automatically configured and loads are transferred automatically...
More data are needed, Could you describe your model or send the file ?

Problem solved! Was very elementary, the coordinates were not set properly and the boundary conditions were messed up. Checked the model pdf and was able to solve it. I'm kinda getting a hang of it now. Thank you.
