Comsol, mechanical damping, not convergence?

When I compute a piezoelectric transducer in a water domain, the solution works well and convergence. However, when I add mechanical damping to the piezoelectric material and keep others all the...

Anybody have experience on simulate the transducer fabricated by 1-3 composites(piezoelectric rods embed in epoxy)?

I simulate the transducer model by comsol. However, the results are weird for the far field level, what I want to know is if it is not easy to simulate this composites? The files are attached.

Why not the far field calculation does not work in Frequency-Domain, Perturbation ?

Hi, I simulate the transducer performance under pre-stressed, and I reference the template "tonpilz transducer prestress" in the library. Far field pressure works under frequency domain, but I can...
