Implement Pzt ansys 2020
 

Hello I'm taking a graduate project about simulation of pzt
To simulate pzt, I'm using ansys static structure, but Unfotunately my ansys is 2020R. through many media I learned how to take pzt. but all of media using above 2021 having 'piezoelectric toolbox...' is there any escape implement pzt in ansys 2020???

From my point of view maybe I have two option
1. Custumizing pzt's property by using 'Custom material Models', Insert all of pzt's property like matrix
2. Using 'Peizoelectric and mems body'
I never know how to using this extension, Can I Implement pzt, If I uses this extension?

Plz give me some hope, even a possibility...
