set a local rhs function evaluation function. This function is called with local vector containing the local vector information PLUS ghost point information. It should compute a result for all local elements and DM will automatically accumulate the overlapping values.

Synopsis#

#include "petscts.h" 
PetscErrorCode DMTSSetRHSFunctionLocal(DM dm, PetscErrorCode (*func)(DM dm, PetscReal t, Vec u, Vec f, PetscCtx ctx), PetscCtx ctx)
