39 * \brief Mesher generating 2D elements on a geometrical face taking
40 * into account pre-existing nodes on face boundaries
42 * Historically, NETGENPlugin_NETGEN_2D is actually 1D-2D, that is why
43 * the class is named NETGENPlugin_NETGEN_2D_ONLY. Renaming is useless as
44 * algorithm field "_name" can't be changed
