TSGetSLES

Returns the SLES (linear solver) associated with a TS (timestepper) context.

Synopsis

#include "petscts.h"  
int TSGetSLES(TS ts,SLES *sles)

Not Collective, but SLES is parallel if TS is parallel

Input Parameter

ts -the TS context obtained from TSCreate()

Output Parameter

sles -the nonlinear solver context

Notes

The user can then directly manipulate the SLES context to set various options, etc. Likewise, the user can then extract and manipulate the KSP and PC contexts as well.

TSGetSLES() does not work for integrators that do not use SLES; in this case TSGetSLES() returns PETSC_NULL in sles.

Keywords

timestep, get, SLES
