You will need to have the right Fortran compiler and a C compiler installed on your machine. For more details, consult the doc available in the archive distributed and on-line (see below).
What free pre and post-processor softwares can be used ?
  • Mesh creators
    • Gmsh, Elmer library mesh generator, Telemac mesh generator, Emc2 (Inria).
  • Visualizers
    • vtk format eg Paraview. Also Tecplot format.
Any documentation ?
Documentations (users / programmers / numerics manuals) are available in the distributed archive (along the source files), consult the "Download" page.
As example an old version is available online (HAL CNRS): pdf file .

Open Online Courses
