[petsc-users] DIVERGED_LINEAR_SOLVE in SNES

[Li Luo]

Dear developer,

I am using SNES for solving a nonlinear system.  For some cases, SNES
diverged -3 with "DIVERGED_LINEAR_SOLVE" when the linear solver reached its
maximum iteration count (i.e -ksp_max_it 10000).
Is that possible to let SNES continue even though the linear solver reaches
the maximum number of iterations? Just take the result at 10000 for the
Jacobian solution and then update the Newton step?

Best,
Li
