Query whether adjacency in the mesh uses the cone or the support first

Synopsis

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

Input Parameter

dm -The DM object

Output Parameter

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 star(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
