Hello everyone

As shown in the figure, the top layer is piezoelectric material and the bottom layer is matrix. If an electric field is applied to the piezoelectric material,

I don’t know how I can push to the weak form of this problem

Yes, it can. Please read the documentation and the examples.

Thank you very much.I am a fresher about FF++.

You ca see with Pascal Ventura for compiling piezo exemple
the mail is : pascal.ventura@univ-lorraine.fr

I’m sorry to bother you again. I follow https://doc.freefem.org/_static/pdf/FreeFEM-doc-v3_Chinese.pdf#section.4.8 See some examples. However, no piezoelectric related examples were found.
