piezoelectric cylindrical tranducer

Hello,

I am currently working in COMSOL. I have built a piezoelectric cylindrical transducer using piezoelectric devices module. Following are my questions

How can I find the breathing mode (lowest mode) frequency of the transducer in free-free condition? i.e the lowest resonant frequency.

How can I find the total electrical, mechanical, kinetic and electromechanical energies?

How can I find the mode shapes for up to 6 modes? I want 1D plots for this.
