hello, When i do a piezoelectric prestresssed frequency simulation,the structure is a thin plate and five meshs in thickness direction, i got the "failed to find a solution maximum number of newton iterations reached" error in the first setp (add residual stress), to solve this problem i use auxiliary sweep to increase the residual stress slowly, the simulation can converge, but the second step the frequency domain result is strange , it had a absolute wrong result. If the auxiliary sweep cause any problem? thank you !
