DMPlexSetAdjacencyUseCone

Define adjacency in the mesh using either the cone or the support first

Synopsis

#include "petscdmplex.h"   
PetscErrorCode DMPlexSetAdjacencyUseCone(DM dm, PetscBool useCone)

Input Parameters

dm - The DM object
useCone - Flag to use the cone first

Notes

    FEM:   Two points p and q are adjacent if q \in closure(star(p)),   useCone = PETSC_FALSE, useClosure = PETSC_TRUE
    FVM:   Two points p and q are adjacent if q \in support(p+cone(p)), useCone = PETSC_TRUE,  useClosure = PETSC_FALSE
    FVM++: Two points p and q are adjacent if q \in star(closure(p)),   useCone = PETSC_TRUE,  useClosure = PETSC_TRUE
