KSPSetErrorIfNotConverged

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

Synopsis

#include "petscksp.h" 
PetscErrorCode  KSPSetErrorIfNotConverged(KSP ksp,PetscBool flg)
Logically Collective on KSP

Input Parameters

ksp - iterative context obtained from KSPCreate()
flg - PETSC_TRUE indicates you want the error generated

Options database keys

-ksp_error_if_not_converged : this takes an optional truth value (0/1/no/yes/true/false) -

Notes

Normally PETSc continues if a linear solver fails to converge, you can call KSPGetConvergedReason() after a KSPSolve() to determine if it has converged.
