DOLFIN-CONVERT, a Python program which can convert a mesh file from Gmsh, MEDIT, METIS or SCOTCH format to an XML format suitable for use by DOLFIN or FENICS, by Anders Logg.
DOLFIN_XML, a data directory which contains examples of XML files that describe 3D finite element method (FEM) meshes as used by DOLFIN and FENICS.
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.
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.
VTU, a data directory which contains examples of VTU files, an XML-based file format used by the Visualization Toolkit for unstructured grids, which can be displayed by the paraview interactive visualization program;
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 extracts two sets of information, namely, the coordinates of nodes, and the indices of nodes that form each element, which constitute an FEM model of the mesh.
