Hi

All the results so, e.g., displacement/stress results and voltages are of interest and can be looked at, once and when applying e.g., a structural force (or voltage excitation) in a coupled field harmonic analysis. So they are ok.

For your model we use a Voltage ground or Voltage =0, and on the top of the PZT use a voltage coupling object (otherwise you get this weird voltage plot like shown in your image)

Finally look at adding damping since at resonance the dyn. response is damped controled by damp. and if no damp. results are not very realistic (they go to infinity in theory when no damp.).

All the best
