FEM_TO_TRIANGLE is a C program which reads FEM files of node coordinates and element connectivity, which define a mesh of a 2D region, divided into triangular elements, and creates a corresponding pair of Triangle files.
These files can be used as input to Triangle for viewing, or mesh refinement.

FEM_IO, a C library which reads or writes node, element and data files defining a model associated with the finite element method (FEM).
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_MEDIT, a C program which reads a pair of FEM files defining node coordinates and elements, and creates a corresponding MEDIT mesh file.
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.
