SNESSetErrorIfNotConverged
Causes SNESSolve() to generate an error if the solver has not converged. 
Synopsis
#include "petscsnes.h"  
PetscErrorCode  SNESSetErrorIfNotConverged(SNES snes,PetscBool flg)
Logically Collective on SNES
Input Parameters
|  | snes | - iterative context obtained from SNESCreate() | 
|  | flg | - PETSC_TRUE indicates you want the error generated | 
Options database keys
-snes_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 SNESGetConvergedReason() after a SNESSolve()
to determine if it has converged.
Keywords
 SNES, set, initial guess, nonzero
