Further work on full dynamics/physics separation.

LMDZ.COMMON:

  • added phy_common/vertical_layers_mod.F90 to store information on vertical grid. This is where routines in the physics should get the information.
  • The contents of vertical_layers_mod intialized via dynphy_lonlat/inigeomphy_mod.F90.

LMDZ.MARS:

  • physics now completely decoupled from dynamics; the physics package may now be compiled as a library (-libphy option of makelmdz_fcm).
  • created an "ini_tracer_mod" routine in module "tracer_mod" for a cleaner initialization of the later.
  • removed some purely dynamics-related outputs (etot0, zoom parameters, etc.) from diagfi.nc and stats.nc outputs as these informations are not available in the physics.

LMDZ.GENERIC:

  • physics now completely decoupled from dynamics; the physics package may now be compiled as a library (-libphy option of makelmdz_fcm).
  • added nqtot to tracer_h.F90.
  • removed some purely dynamics-related outputs (etot0, zoom parameters, etc.) from diagfi.nc and stats.nc outputs as these informations are not available in the physics.

LMDZ.VENUS:

  • physics now completely decoupled from dynamics; the physics package may now be compiled as a library (-libphy option of makelmdz_fcm).
  • added infotrac_phy.F90 to store information on tracers in the physics. Initialized via iniphysiq.
  • added cpdet_phy_mod.F90 to store t2tpot etc. functions to be used in the physics. Initialized via iniphysiq. IMPORTANT: there are some hard-coded constants! These should match what is in cpdet_mod.F90 in the dynamics.
  • got rid of references to moyzon_mod module within the physics. The required variables (tmoy, plevmoy) are passed to the physics as arguments to physiq.

LMDZ.TITAN:

  • added infotrac_phy.F90 to store information on tracers in the physics. Initialized via iniphysiq.
  • added cpdet_phy_mod.F90 to store t2tpot etc. functions to be used in the physics.
  • Extra work required to completely decouple physics and dynamics: moyzon_mod should be cleaned up and information passed from dynamics to physics as as arguments. Likewise moyzon_ch and moyzon_mu should not be queried from logic_mod (which is in the dynamics).
