points on the boundary of the surface. The ordering of these point numbers points on the boundary of the surface. The ordering of these point numbers
defines the ordering and orientation of the mesh elements, and should thus defines the ordering and orientation of the mesh elements, and should thus
follow the node ordering for triangles or quadrangles given in @ref{Gmsh follow the node ordering for triangles or quadrangles given in @ref{Gmsh

oriented when the mesh is not recombined.
