Last change on this file since 3871 was 2311, checked in by Ehouarn Millour, 9 years ago

Further modifications to enforce physics/dynamics separation:

  • moved iniprint.h and misc_mod back to dyn3d_common, as these should only be used by dynamics.
  • created print_control_mod in the physics to store flags prt_level, lunout, debug to be local to physics (should be used rather than iniprint.h)
  • created abort_physic.F90 , which does the same job as abort_gcm() did, but should be used instead when in physics.
  • reactivated inifis (turned it into a module, inifis_mod.F90) to initialize physical constants and print_control_mod flags.
