DMTSSetIJacobianContextDestroy

set TS Jacobian evaluation context destroy function into a DMTS

Synopsis

#include "petscts.h" 
PetscErrorCode DMTSSetIJacobianContextDestroy(DM dm, PetscCtxDestroyFn *f)

Not Collective

Input Parameters

• dm - DM to be used with TS

• f - Jacobian evaluation context destroy function, see PetscCtxDestroyFn for its calling sequence

Note

TSSetIJacobianContextDestroy() is normally used, but it calls this function internally because the user context is actually associated with the DM. This makes the interface consistent regardless of whether the user interacts with a DM or not.

Developer Notes

If DM took a more central role at some later date, this could become the primary method of setting the Jacobian.
