#include "petscdmda.h" #include "petscsnes.h" PetscErrorCode DMDASNESSetFunctionLocal(DM dm,InsertMode imode,PetscErrorCode (*func)(DMDALocalInfo*,void*,void*,void*),void *ctx)Logically Collective
| 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 |
| info | - DMDALocalInfo defining the subdomain to evaluate the residual on | |
| x | - dimensional pointer to state at which to evaluate residual (e.g. PetscScalar *x or **x or ***x) | |
| f | - dimensional pointer to residual, write the residual here (e.g. PetscScalar *f or **f or ***f) | |
| ctx | - optional context passed above |
