FEM_TO_MEDIT is a C++ program which reads a set of FEM files defining the node coordinates, boundary nodes, and elements of a finite element mesh, and rewrites the data as a MEDIT mesh file.
The program can convert 2D meshes of triangles, or 3D meshes of tetrahedrons.

FEM_TO_GMSH, a C++ 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_TRIANGLE, a C++ 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.
FEM_TO_XML, a C++ program 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.
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.
MEDIT, a data directory which contains examples of files which can be used by the MEDIT program to define a 2D or 3D mesh for use by the finite element method (FEM), using triangles, quadrilaterals, tetrahedrons or hexahedrons.
MEDIT, examples which illustrate the use of medit, an interactive graphics program developed to visualize numerical simulation results on unstructured meshes in two and three dimensions. Scalar, vector and tensor fields can be easily associated and displayed with meshes. The program is by Pascal Frey.
MEDIT_TO_FEM, a C++ program which reads a mesh file created by the MEDIT program and writes a corresponding pair of node and element files that correspond to the FEM format.
TRIANGLE_TO_MEDIT, a C++ program which reads the NODE and ELE files created by triangle() to describe a triangular mesh, and writes a corresponding MESH file for input to medit().
ELL is a 2D L-shaped region, with a grid of 65 nodes and 96 elements of order 3 triangles.
P01 is 3D FEM data for a rectangular channel of dimensions 3x1x1 physical units, using 584 nodes and 2568 tetrahedral elements.
