TETHEX: examples which illustrate the use of TETHEX, a C++ program which can read a Gmsh file defining a mesh of triangles or tetrahedrons, and subdivide the mesh into quadrilaterals or hexahedrons, which are suitable for use by the DEALII finite element program, by Mikhail Artemiev.

DOLFIN-CONVERT, a Python program which can convert mesh file from Gmsh, MEDIT, METIS or SCOTCH format to an XML format suitable for use by DOLFIN or FENICS, by Anders Logg.
MSH, a data directory of examples of MSH files, the native 3D mesh format used by gmsh.
TET_MESH_TO_GMSH, a C++ program which reads information defining a tet mesh, namely a file of node coordinates and a file of elements defined by node indices, and creates a corresponding Gmsh mesh file.
TRIANGULATION_TO_GMSH, a C++ program which reads information defining a trinagulation, namely a file of node coordinates and a file of elements defined by node indices, and creates a corresponding Gmsh mesh file.
A brief explanantion, and the current source code for tethex are available at http://code.google.com/p/tethex/wiki/Tethex.
RECTANGLE is a simple mesh of a 2D rectangle. It was created by the MESH2D program, and written out as two files, one of node coordinates and one of triples of node indices that define a triangle. These two files were read by triangulation_to_gmsh, which converted them to a single msh file. Then tethex was used to convert the msh file of triangles into an msh file of quadrilaterals.
