TSGetKSP#
Returns the KSP (linear solver) associated with a TS (timestepper) context.
Synopsis#
#include "petscts.h"
PetscErrorCode TSGetKSP(TS ts, KSP *ksp)
Not Collective, but ksp is parallel if ts is parallel
Input Parameter#
Output Parameter#
ksp - the nonlinear solver context
Notes#
The user can then directly manipulate the KSP context to set various
options, etc. Likewise, the user can then extract and manipulate the
PC context as well.
TSGetKSP() does not work for integrators that do not use KSP;
in this case TSGetKSP() returns NULL in ksp.
