Insert boundary values into a local vector

Synopsis

#include "petscdmplex.h"   
PetscErrorCode DMPlexInsertBoundaryValuesEssential(DM dm, PetscReal time, PetscInt field, PetscInt Nc, const PetscInt comps[], DMLabel label, PetscInt numids, const PetscInt ids[], PetscErrorCode (*func)(PetscInt, PetscReal, const PetscReal[], PetscInt, PetscScalar *, void *), void *ctx, Vec locX)

Input Parameters

dm - The DM, with a PetscDS that matches the problem being constrained
time - The time
field - The field to constrain
Nc - The number of constrained field components, or 0 for all components
comps - An array of constrained component numbers, or NULL for all components
label - The DMLabel defining constrained points
numids - The number of DMLabel ids for constrained points
ids - An array of ids for constrained points
func - A pointwise function giving boundary values
ctx - An optional user context for bcFunc

Output Parameter

locX -A local vector to receives the boundary values
