DMPlexComputeBdIntegral

Form the integral over the specified boundary from the global input X using pointwise functions specified by the user

Synopsis

#include "petscdmplex.h"   
PetscErrorCode DMPlexComputeBdIntegral(DM dm, Vec X, DMLabel label, PetscInt numVals, const PetscInt vals[], void (**funcs)(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[]), PetscScalar *integral, void *user)

Input Parameters

• dm - The mesh

• X - Global input vector

• label - The boundary DMLabel

• numVals - The number of label values to use, or PETSC_DETERMINE for all values

• vals - The label values to use, or NULL for all values

• funcs - The functions to integrate along the boundary for each field

• user - The user context

Output Parameter
