The directions for use of CESAM2k V1.0 (in french) can be found in the compressed files: aide_mem2k.ps.gz First uncompress the file: gunzip aide_mem2k.ps.gz second edit, e.g. with ghostview, and/or print (about 80 pages). The source (F95) of the code is in the compressed ASCII file: CESAM2k_V1.1.tar.gz First uncompress the file: gunzip CESAM2k_V1.1.tar.gz second: tar -xvf CESAM2k_V1.1.tar Ones obtains the sub-directories in the file CESAM2k_V1: NOTICE.tar.gz TESTS.tar.gz SCRIPTS.tar.gz SOURCE.tar.gz EXPLOIT.tar.gz SUN_STAR_DATA.tar.gz The ASCII source of cesam is in the sub-directory SOURCE Programs for tests are in the sub-directory TESTS In the sub-directory EXPLOIT one found examples of FORTRAN programs and UNIX procedures to exploit the code Initial models in ASCII, and physical data are in the sub-directory SUN_STAR_DATA The directions for use give detailled explanations how to implant the source in UNIX machine.
