set a local residual evaluation function

Synopsis

#include "petscdmda.h" 
#include "petscsnes.h" 
PetscErrorCode DMDASNESSetFunctionLocal(DM dm,InsertMode imode,PetscErrorCode (*func)(DMDALocalInfo*,void*,void*,void*),void *ctx)
Logically Collective

Input Arguments

dm - DM to associate callback with
imode - INSERT_VALUES if local function computes owned part, ADD_VALUES if it contributes to ghosted part
func - local residual evaluation
ctx - optional context for local residual evaluation

Calling sequence for func

info - DMDALocalInfo defining the subdomain to evaluate the residual on
x - dimensional pointer to state at which to evaluate residual
f - dimensional pointer to residual, write the residual here
ctx - optional context passed above
