void add_boundary_ghosts(MeshBase &mesh)
Adds a new layer of "ghost" elements along the domain boundaries.
void tag_boundary_ghosts(MeshBase &mesh)
Flags the outermost element layer along the domain boundaries as "ghost" elements.

MeshBase & mesh
void all_subdivision(MeshBase &mesh)
Turns a triangulated mesh into a subdivision mesh.
The libMesh namespace provides an interface to certain functionality in the library.
This is the MeshBase class.

void find_one_ring(const Tri3Subdivision *elem, std::vector< const Node * > &nodes)
Determines the 1-ring of element elem, and writes it to the nodes vector.
void prepare_subdivision_mesh(MeshBase &mesh, bool ghosted=false)
Prepares the mesh for use with subdivision elements.
