Last change on this file was 3242, checked in by idelkadi, 7 years ago

Nettoyage du code :

  • changement de nomes des routines pour avoir les memes nome des modules
  • corrections
  • dos2unix appliquee aux fichiers
  • Rajouter "implicit none" pour les routines ne le comportant pas
  • Suppression des commentaires unitils

Corrections pour tourner en mode debug :

controle par la cles ok_debug_cosp dans mod_cosp_constants.F90
la valeur par defaut etant .false.
