DMTSGetRHSJacobian#

get TS Jacobian evaluation function from a DMTS

Synopsis#

#include "petscts.h" 
PetscErrorCode DMTSGetRHSJacobian(DM dm, TSRHSJacobianFn **func, void **ctx)

Not Collective

Input Parameter#

dm - DM to be used with TS

Output Parameters#

func - Jacobian evaluation function, for calling sequence see TSRHSJacobianFn
ctx - context for residual evaluation

Note#

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