SNESSetErrorIfNotConverged

Causes SNESSolve() to generate an error immediately if the solver has not converged.

Synopsis

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

Logically Collective

Input Parameters

• snes - iterative context obtained from SNESCreate()

• flg - PETSC_TRUE indicates you want the error generated

Options Database Key

• -snes_error_if_not_converged <true,false> - cause an immediate error condition and stop the program if the solver does not converge

Note

Normally PETSc continues if a solver fails to converge, you can call SNESGetConvergedReason() after a SNESSolve() to determine if it has converged. Otherwise the solution may be inaccurate or wrong
