Hi all, I am trying to model a piezo actuator deforming steel membrane using piezoelectric and structural physics domains. My model has piezo ring and a steel membrane. I have a piezo electric effect under my Multiphysics tab and when I try to solve this I end up in some deflection but when I have same piezo electric effect added twice under my Multiphysics my result doubles and increases further with adding more piezo electric effect I am not really sure on how this should result in the output.

1. Should I be using 1 or 2 piezo electric effects in Multiphysics? Would this depend on the number of piezo used in the model

2. When I apply a voltage the voltage profile on the piezo is not uniform and seems to be distorted. Can anyone help me with this problem?

Thanks and Regards,
Anand T
