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.

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.
