Division by zero error in multiphysics model (piezo+acoustic)

Attached to this post you can find an example of piezoelectric transducer.
First of all, I've created the geometry of the piezo transducer, and I covered it with a sphere of water. The spere is double-layered, to make a matching layer.
Then, I've set the boundary conditions, and for the piezo boundaries, I've set the normal acceleration in the acoustic module, using the acceleration from the piezo. for the mechanic model, I've set the pressure load of boundaries, using the pressure of the acoustic model.
When I studi the behavior for a single frequency, I got an error, and I don't know what the error means. Can you help me to solve this? Thanks in advantage
Daniele
