TET_MESH_TO_GMSH
Convert Tet Mesh Files to GMSH MSH Format


TET_MESH_TO_GMSH, a C++ code which converts a pair of files defining a tetrahedral mesh into an equivalent file using the Gmsh msh format.

In particular, TET_MESH_TO_GMSH reads a node coordinate file listing the coordinates of a set of 3D points, and an element file list sets of 4, 10 or 20 nodes that form tetrahedral elements. It creates a single equivalent file in the Gmsh msh format.

Usage:

tet_mesh_to_gmsh prefix
