The directions for use of CESAM5 (in french) can be found in the compressed files: cesam.ps.gz First decompress the file: gunzip cesam.ps.gz second edit, e.g. with ghostview, and/or print (about 230 pages). The source of the code is in the compressed ASCII file: CESAM5.tar.gz First decompress the file: gunzip CESAM5.tar.gz second: tar -xvf CESAM5.tar The ASCII source of cesam is in the subdirectory SOURCE Programs for tests are in the subdirectory TESTS In the subdirectory EXPLOIT one found examples of FORTRAN programs and UNIX procedures to exploit the code Initial models in ASCII, and physical data are in the subdirectory SUN_STAR_DATA Chapter 2 of the direction for use gives detailled explanations how to implant the source in UNIX machine.
