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
