DMDASNESSetObjectiveLocalVec#

set a local residual evaluation function that operates on a local vector with DMDA

Synopsis#

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

Logically Collective

Input Parameters#

  • dm - DM to associate callback with

  • func - local objective evaluation, see DMDASNESSetObjectiveLocalVec 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 - state vector at which to evaluate the objective

  • obj - returned objective value for the local subdomain

  • ctx - optional context passed above
