I'm a quite new user in Comsol, and I have some doubts about the Piezoelectric Devices (pzd) Module.
I have built a model with 2 ceramic rings (see the model in the attached file), that are suposed to create an axial vibration to the transducer. In order to obtain that, the two ceramic rings are polarized in the opposite directions. Hower, the result is not what I am looking for.
I have tried polarizing the ceramics in different ways, but no way.
It is suposed that the axial vibration created with the first ceramic added to the vibration createeed with the second, the effect is going to be double, and then, this is going to be transmited to the elastic cylinders coupled.
How would you define the coupling in this case? I am not sure if I have to use a pair in this case or not.
Any help to solve this strange result will be very grateful
Thanks a lot
