fem_to_medit, a Fortran90 code which reads a pair of FEM files defining the node coordinates and elements of a finite element mesh, and rewrites the data as a medit() MESH file.
The code can convert 2D meshes of triangles, or 3D meshes of tetrahedrons.

fem_to_medit is available in a C version and a C++ version and a Fortran90 version and a MATLAB version and an Octave version.
fem2d, a data directory which contains examples of 2D FEM files, text files that describe a 2D finite element geometry and associated nodal values;
fem3d, a data directory which contains examples of 3D FEM files, three text files that describe a 3D finite element geometry and associated nodal values.
mesh, a data directory which contains examples of MESH files, which can be used to define the geometry of a finite element mesh in 2D or 3D, using triangles, quadrilaterals, tetrahedrons or hexahedrons.
tet_mesh_boundary, a Fortran90 code which returns the nodes and faces of the boundary of a tetrahedral mesh, which themselves form a 3D triangular mesh or TRI_SURFACE.
triangulation_boundary_nodes, a Fortran90 code which reads data defining a triangulation, determines which nodes lie on the boundary, and writes their coordinates to a file.
