iluckyyang / FEconv

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), VTK files (.vtk), etc. If you use a Modulef format 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).

1. Description

Program feconv converts finite element (FE) mesh files between several formats; it can also transform the FE type of the mesh and/or perform a bandwidth optimization. Some conversion capabilities are also present for mesh fields. Please, visit the EXAMPLES section, in the help invoked by feconv -h, to know more details.

2. Installation

To install this program, you must have previously installed make in your system and a Fortran 2003 compiler. At the present time, only the GNU Fortran compiler, gfortran, and the Intel Fortran compiler, ifort, are supported. Go to http://sourceforge.net/projects/feconv/ and download the package feconv_.tar.gz, where is the date of the release. Open a terminal in Linux or Mac OS X, or a Command Window in Windows, go to the installation folder and type:

    make -f Makefile.<compiler>.<os>

where can be "gfortran" or "ifort" and can be "linux" or "windows" (for Mac OS X, "linux" is the valid option).
