DMTSSetRHSJacobian#
set TS Jacobian evaluation function into a DMTS
Synopsis#
#include "petscts.h"
PetscErrorCode DMTSSetRHSJacobian(DM dm, TSRHSJacobianFn *func, void *ctx)
Not Collective
Input Parameters#
func - Jacobian evaluation routine, for calling sequence see
TSIJacobianFnctx - context for residual evaluation
Note#
TSSetRHSJacobian() 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.
