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
