virtual UniquePtr< Elem > build_side_ptr(const unsigned int i, bool proxy=true)=0
A Node is like a Point, but with more information.
Definition: node.h:52
The Face is an abstract element type that lives in two dimensions.
Definition: face.h:37
This is the base class from which all geometric element types are derived.
Definition: elem.h:89
The libMesh namespace provides an interface to certain functionality in the library.

virtual UniquePtr< Elem > build_edge_ptr(const unsigned int i) libmesh_override
build_side and build_edge are identical for faces.

virtual bool is_edge_on_side(const unsigned int e, const unsigned int s) const libmesh_override
is_edge_on_side is trivial in 2D.
