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
ts -the TS context obtained from TSCreate()
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
KSP and PC contexts as well.
TSGetKSP() does not work for integrators that do not use KSP;
in this case TSGetKSP() returns NULL in ksp.
