DMPlexInsertBoundaryValuesRiemann#

Insert boundary values into a local vector

Synopsis#

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

Input Parameters#

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

  • time - The time

  • faceGeometry - A vector with the FVM face geometry information

  • cellGeometry - A vector with the FVM cell geometry information

  • Grad - A vector with the FVM cell gradient information

  • 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

Note#

This implementation currently ignores the numcomps/comps argument from DMAddBoundary()
