TSGetSNES
Returns the SNES (nonlinear solver) associated with a TS (timestepper) context. Valid only for nonlinear problems.
Synopsis
#include "petscts.h"
PetscErrorCode TSGetSNES(TS ts,SNES *snes)
Not Collective, but SNES is parallel if TS is parallel Many br
Input Parameter
ts -the TS context obtained from TSCreate() Many br
Output Parameter
snes -the nonlinear solver context Many br
Notes
The user can then directly manipulate the SNES context to set various Many broptions, etc. Likewise, the user can then extract and manipulate the Many brKSP, KSP, and PC contexts as well. Many br
TSGetSNES() does not work for integrators that do not use SNES; in Many brthis case TSGetSNES() returns NULL in snes. Many br
