SNESSetKSP#

Sets a KSP context for the SNES object to use

Synopsis#

#include "petscsnes.h"  
PetscErrorCode SNESSetKSP(SNES snes, KSP ksp)

Not Collective, but the SNES and KSP objects must live on the same MPI_Comm

Input Parameters#

  • snes - the SNES context

  • ksp - the KSP context

Notes#

The SNES object already has its KSP object, you can obtain with SNESGetKSP() so this routine is rarely needed.

The KSP object that is already in the SNES object has its reference count decreased by one when this is called.
