snes converged reason for newton trust region?

[Gary Hu]

Hello Group,

When I use -snes_type newtontr

I sometimes get CONVERGED_TR_DELTA instead of CONVERGED_FNORM.

My guess is that the trust region size keeps reducing until it becomes smaller than the tolerance.

Is there a way to force the algorithm to converge only due to FNORM?

Thanks,

Gary

I have zero experience on the trust region Newton. I would like PETSc Team  chime in.

Fande,
