Hi, I wonder how to set the solvers.

Hi, I got the mail box following
Error:
Failed to find a solution:
Maximum number of Newton iterations reached.
Returned solution has not converged.
So I wonder what the set of solver is suitable.
This is my setting.
GMRES
Incomplete LU 5E-4
Relative tolerance 1.0E-2
Maximum number of iterations 800
If you know the proper setting of the solver for computation,
Let me know, please.
Thanks
