fem_to_gmsh, a FORTRAN90 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 code 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 FORTRAN90 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 code.
FEM_TO_XML, a FORTRAN90 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 code, a 3D mesh generator for the finite element method (FEM).
GMSH_IO, a FORTRAN90 code which can read or write some of the files created by the Gmsh code for 1D, 2D or 3D meshes used by the finite element method (FEM).
MSH, a data directory of examples of MSH files, the native 3D mesh format used by Gmsh.
