DMPlexInsertBoundaryValuesEssentialBdField

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

Synopsis

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

Collective

Input Parameters

• dm - The DM, with a PetscDS that matches the problem being constrained

• time - The time

• locU - A local vector with the input solution values

• 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, the calling sequence is given in DMProjectBdFieldLabelLocal()

• ctx - An optional user context for func

Output Parameter

• locX - A local vector to receive the boundary values
