All models: Reorganizing the physics/dynamics interface.

  • makelmdz and makelmdz_fcm scripts adapted to handle the new directory settings
  • misc: (replaces what was the "bibio" directory)
  • Should only contain extremely generic (and non physics or dynamics-specific) routines
  • Therefore moved initdynav.F90, initfluxsto.F, inithist.F, writedynav.F90, write_field.F90, writehist.F to "dyn3d_common"
  • dynlonlat_phylonlat: (new interface directory)
  • This directory contains routines relevent to physics/dynamics grid interactions, e.g. routines gr_dyn_fi or gr_fi_dyn and calfis
  • Moreover the dynlonlat_phylonlat contains directories "phy*" corresponding to each physics package "phy*" to be used. These subdirectories should only contain specific interfaces (e.g. iniphysiq) or main programs (e.g. newstart)
  • phy*/dyn1d: this subdirectory contains the 1D model using physics from phy*
