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 Many br
Input Parameters
| ksp | - iterative context obtained from KSPCreate() Many br |
| flg | - PETSC_TRUE indicates you want the error generated Many br |
Options database keys
-ksp_error_if_not_converged : this takes an optional truth value (0/1/no/yes/true/false) - Many br Many br
Notes
Normally PETSc continues if a linear solver fails to converge, you can call KSPGetConvergedReason() after a KSPSolve() Many brto determine if it has converged. Many br
