fem_to_gmsh, a C code which converts FEM files representing a 1D, 2D, or 3D mesh into a GMSH mesh file.
The FEM files include a node file, which simply lists the coordinates of each node, and an element connectivity file, which lists, for each element, the indices of the nodes that define it. Either 0 or 1-based indexing can be used when referencing the nodes.

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.
FEM_TO_TRIANGLE, a C code which reads FEM files defining a 2D mesh of triangles, namely a file of node coordinates and a file of elements defined by node indices, and creates a corresponding pair of node and element files for use by Jonathan Shewchuk's triangle program.
FEM_TO_XML, a C code which reads FEM files defining a 1D, 2D or 3D mesh, namely a file of node coordinates and a file of elements defined by node indices, and creates a corresponding XML file for input to DOLFIN or FENICS.
GMSH, examples which illustrate the use of the Gmsh program, a 3D mesh generator for the finite element method (FEM).
GMSH_IO, a C code which can read or write some of the files created by the Gmsh program for 1D, 2D or 3D meshes used 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.
TET_MESH, a C code which carries out various operations on tetrahedral meshes.
TRIANGULATION, a C code which performs various operations on order 3 (linear) or order 6 (quadratic) triangulations.
