SNESSetJacobianDomainError

tells SNES that the function you provided to SNESSetJacobian() at the proposed step. For example there is a negative element transformation.

Synopsis

#include "petscsnes.h"  
PetscErrorCode SNESSetJacobianDomainError(SNES snes)

Logically Collective

Input Parameter

• snes - the SNES context

Notes

If this is called the SNESSolve() stops iterating and returns with a SNESConvergedReason of SNES_DIVERGED_FUNCTION_DOMAIN

You should always call SNESGetConvergedReason() after each SNESSolve() and verify if the iteration converged (positive result) or diverged (negative result).

You can direct SNES to avoid certain steps by using SNESVISetVariableBounds(), SNESVISetComputeVariableBounds() or SNESLineSearchSetPreCheck(), SNESLineSearchSetPostCheck()
