tet_mesh_to_gmsh, an Octave code which converts a pair of files defining a tetrahedral mesh into an equivalent file using the gmsh() MSH format.
The code reads a node coordinate file listing the coordinates of a set of 3D points, and an element file list of sets of 4, 10 or 20 nodes that form tetrahedral elements. It creates a single equivalent file in the gmsh() MSH format.
