DMPlexInsertBoundaryValuesEssential

Insert boundary values into a local vector using a function of the coordinates

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
