DMDASNESSetObjectiveLocal

set a local residual evaluation function to used with a DMDA

Synopsis

#include "petscdmda.h" 
#include "petscsnes.h" 
PetscErrorCode DMDASNESSetObjectiveLocal(DM dm, PetscErrorCode (*func)(DMDALocalInfo *info, void *x, PetscReal *obj, void *), void *ctx)

Logically Collective

Input Parameters

• dm - DM to associate callback with

• func - local objective evaluation, see DMDASNESSetObjectiveLocal for the calling sequence

• ctx - optional context for local residual evaluation

Calling sequence of func

• info - DMDALocalInfo defining the subdomain to evaluate the Jacobian at

• x - dimensional pointer to state at which to evaluate the objective (e.g. PetscScalar *x or **x or ***x)

• obj - returned objective value for the local subdomain

• ctx - optional context passed above
