Program feconv is an utility to convert between several mesh and FE field formats, like ANSYS mesh files (.msh), MD Nastran input files (.bdf), I-Deas Universal (.unv) and VTK files (.vtk). The program uses an own format related with Modulef to store an intermediate mesh (.mfm).  It can transform the FE type of a mesh composed of trangles or tetrahedra, to Lagrange P1 or P2, Raviart-Thomas (face) or Whitney (edge) finite elements.  It also uses third-party code to perform bandwidth optimization (CutlHill-McKee optimization).
