Comsol, mechanical damping, not convergence?

08 May 2017 1 8K Report

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 same, the solution can not convergence, I am wondering why?

Manigandan Sekar

This happens due to lack of interaction between the dampers to transducer
