The manual's "MSH ASCII file format" refers to 20-node third order tetrahedra
and a 30-node fourth order tetrahedra.  Yet, I haven't figured out how to use
Gmsh to generate meshes which included those elements nor are those elements
covered in the manual's node ordering section.

So, is it possible to generate meshes of these tetrahedra with Gmsh?  If so,

yes

could anyone explain how it's done and what's the node ordering for these
elements?


cf. Geo/MTetrahedron.h in the source code


Thanks in advance,
