Input Parameter
ts -the TS context obtained from TSCreate() Many br
Output Parameter
ksp -the nonlinear solver context Many br
Notes
The user can then directly manipulate the KSP context to set various Many broptions, etc. Likewise, the user can then extract and manipulate the Many brKSP and PC contexts as well. Many br
TSGetKSP() does not work for integrators that do not use KSP; Many brin this case TSGetKSP() returns NULL in ksp. Many br
