SNESSetCheckJacobianDomainError

tells SNESSolve() whether to check if the user called SNESSetJacobianDomainError() to indicate a Jacobian domain error after each Jacobian evaluation.

Synopsis

#include "petscsnes.h"  
#include "petscsnes.h"  
PetscErrorCode SNESSetCheckJacobianDomainError(SNES snes, PetscBool flg)

Logically Collective

Input Parameters

• snes - the SNES context

• flg - indicates if or not to check Jacobian domain error after each Jacobian evaluation

Notes

By default, it checks for the Jacobian domain error in the debug mode, and does not check it in the optimized mode.

Checks require one extra parallel synchronization for each Jacobian evaluation
