Let's me be honest: I have not worked on a piezoelectric/ultrasonic device where simulation of piezoelectric physics was necessary for the design of the device. But I have worked on projects where simulating the piezoelectric converse effect was a distraction.

Yes, simulating piezoelectric physics makes your simulation more complete, but it does not make it correct. Dissimilarities between experiments and simulations exist that will never be explained by linear piezoelectric constitutive equations.



If I were faced with a choice to be complete (use piezo physics simulation) or be clever (simulate what is necessary in order to get to experiments), I would always choose to be clever.
