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.
