piezoelectric potential of a material structure after thermal deformation

Please login with a confirmed email address before reporting spam

I want to simulate the piezoelectric potential of a material, which is in contact with other non-piezoelectric materials, after a simulated deformation due to a thermal cooldown.

The thermal deformation part isn't the problem. But then I wonder how to set the initial stress of the deformed structure in order to get the piezoelectric potential? Instead of that the piezoelectric device physics gives me an additional deformation due to the calculated piezoelectric potential, which is therefor compensated and everywhere zero. How can I prevent the piezoelectric deformation in order to see the piezoelectric potential?

Any suggestions? To understand my problem in more detail I attached my mph-file. But you still have to do the computation, because of the attachment filesize limitation.
