but I did not catch the chance to ask my problem about comsol,,

So, I wanna ask my question once again

when I analyze piezoelectric actuator,
the model (d31) is cantilever beam, what I want to do is applying voltage to electrode,

but
Failed to find a solution.
The relative error (84) is greater than the relative tolerance.
Returned solution is not converged.

actually I tried to troubleshoot this error,
changing mesh size, modifying telerance,,,,, there is no answer

if there are some expert, please reply
