fem_to_xml, a FORTRAN77 code which reads FEM files of node coordinates and element connectivity, which define a mesh of a 1D, 2D, or 3D region and creates a corresponding dolfin() XML file.
These mesh files can be used as input to DOLFIN or FENICS.

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_GMSH, a FORTRAN77 program 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.
FEM_TO_MEDIT, a FORTRAN77 program which reads a pair of FEM files defining node coordinates and elements, and creates a corresponding MEDIT mesh file.
FEM_TO_TRIANGLE, a FORTRAN77 program 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.
FENICS, programs which illustrate the use of a collection of free software with an extensive list of features for automated, efficient solution of differential equations.
MITCHELL_FENICS, examples which illustrate the implementation of the Mitchell 2D elliptic partial differential equation (PDE) test problems using FENICS.
TET_MESH, a FORTRAN77 library which carries out various operations on tetrahedral meshes.
TRIANGULATION, a FORTRAN77 library which performs various operations on order 3 (linear) or order 6 (quadratic) triangulations.
XML, a data directory which contains examples of XML files, a standard, general datafile format.
XML_TO_FEM, a Python program which reads an XML file created by FENICS or DOLFIN, describing a mesh in 1D, 2D, or 3D, and creates corresponding FEM files, namely, a file of node coordinates, and a file of element connectivities.
