Last change on this file since 1777 was 1543, checked in by emillour, 9 years ago

All models: Further adaptations to keep up with changes in LMDZ5 concerning
physics/dynamics separation:

  • dyn3d:
  • adapted gcm.F so that all physics initializations are now done in iniphysiq.
  • dyn3dpar:
  • adapted gcm.F so that all physics initializations are now done in iniphysiq.
  • updated calfis_p.F to follow up with changes.
  • copied over updated "bands.F90" from LMDZ5.
  • dynphy_lonlat:
  • calfis_p.F90, mod_interface_dyn_phys.F90, follow up of changes in phy_common/mod_* routines
  • phy_common:
  • added "geometry_mod.F90" to store information about the grid (replaces phy*/comgeomphy.F90) and give variables friendlier names: rlond => longitude , rlatd => latitude, airephy => cell_area, cuphy => dx , cvphy => dy
  • added "physics_distribution_mod.F90"
  • updated "mod_grid_phy_lmdz.F90", "mod_phys_lmdz_mpi_data.F90", "mod_phys_lmdz_para.F90", "mod_phys_lmdz_mpi_transfert.F90", "mod_grid_phy_lmdz.F90", "mod_phys_lmdz_omp_data.F90", "mod_phys_lmdz_omp_transfert.F90", "write_field_phy.F90" and "ioipsl_getin_p_mod.F90" to LMDZ5 versions.
  • phy[venus/titan/mars/std]:
  • removed "init_phys_lmdz.F90", "comgeomphy.F90"; adapted routines to use geometry_mod (longitude, latitude, cell_area, etc.)
