Hello there.

Firstly, maybe you need to learn about which ANSYS WB extension that can be useful to solve your piezoelectric problem. And I think Piezo and MEMS extension is suitable for it. If you need more information, you can create a free student account then go to the following link

And if you need the extension file, you can download it from the following link freely.

Hope this helps!
