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

there is one part in the help specifically for selecting preconditioners and solvers.
Refer to that part, it may help.
