DOLFIN-CONVERT, a Python program which can convert a mesh file from Gmsh, MEDIT, METIS or SCOTCH format to an XML format suitable for use by DOLFIN or FENICS, by Anders Logg.
FEM_TO_GMSH, a C code which reads FEM files definining a 1D, 2D or 3D mesh, namely a file of node coordinates and a file of elements defined by node indices, and creates a Gmsh mesh file.
GMSH, examples which illustrate the use of the Gmsh program, a 1D, 2D or 3D mesh generator that can create meshes suitable for use by the finite element method (FEM).
GMSH_TO_FEM, a C code which reads a mesh data file created by the GMSH program and writes a pair of node and element files that correspond to the FEM format.
MSH, a data directory of examples of MSH files, the native 3D mesh format used by Gmsh.
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.
