I am doing a multiphysics simulation. When I solve it for small voltages COMSOL can solve it, but when I increase the voltage I recieve the message

Time 38.90540034655847:
Repeated error test failures. May have reached a
singularity.
Last time step is not converged.

for sure I do not have singularity in my expressions.

What do you think the problem is?
