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.
Keywords
