Here, in the invoked programs and file formats are the following :
- MDF is the actual format defined in OFELI
- EasyMesh is a free program that generates two dimensional, unstructured, Delaunay
and constrained Delaunay triangulations in general domains. It can be downloaded from the site :
http://www-dinma.univ.trieste.it/nirftc/research/easymesh/Default.htm
- Gnuplot is a command-line driven program for producing 2D and 3D plots. It is under
the GNU General Public License. Available information can be found in the site :
www.gnuplot.info/
- BAMG is a 2-D mesh generator. It allows to construct adapted meshes from a given
metric. It was developed at INRIA, France. Available information can be found in the site :
www-rocq1.inria.fr/gamma/cdrom/www/bamg/eng.htm
- Gambit is a commercial mesh generator. Available information can be
found in the site :
http://fluent.com/software/gambit/
- Gmsh is a free three-dimensional finite element mesh generator with built-in pre- and post-processing
facilities. It can be downloaded from the site :
www.geuz.org/gmsh/
- Tecplot is high quality post graphical commercial processing program developed by
Amtec. Available information can be found in the site :
www.tecplot.com
- Matlab is a language of scientific computing including visualization. It is developed
by MathWorks. Available information can be found in the site :
www.mathworks.com/products/matlab/
- VTK is an open source library of graphical processing. It is developed
by kitware. Graphical postprocessing can be obtained by software
MayaVi or Paraview
for instance.
The optional argument is an integer that defines the (constant) number of degrees of freedom per node.
This information is indeed not always available from mesh generators and is needed in MDF format.
Its default value is 1.
A field file converter : cfield
The command line of the program is :
