I have read the Comsol documentation but i did not get it. I should use weak form pde to model my problem. the equation is attached in Fig. (equ). This is equation of piezoelectric movement.
Tij=0 in this case. All capital parameters are constant
Hello Mrs. Daneshpajooh,
For coincidence, will be a webinar about it:
