PetscErrorCode DMPlexPointGlobalRef(DM dm, PetscInt point, PetscScalar *array, void *ptr)
Not Collective
Input Parameters#
dm -
DM
defining topological spacepoint - topological point
array - array to index into
Output Parameter#
ptr - address of reference to point data, type generic so user can place in structure; returns NULL if global point is not owned
