  • Add parallel capability for ce0l.
  • Small bug in grid_noro fixed (smoothed topography was used instead of unsmoothed one for geopotential computation at north pole).
  • Removed average of mass at poles in etat0dyn_netcdf after start_init_dyn => different results in the zoomed grid case.
  • ok_etat0=n and ok_limit=y combination now works fine (if no initial state is needed, but only limit.nc file). This required:
    • to move grid_noro0 and start_init_noro0 subroutines from etat0dyn_netcdf.F90 to limit_netcdf.F90
    • to create init_ssrf_m.F90 file, so that sub-surfaces can be initialized from limit_netcdf.F90 without any etat0*_netcdf routines call).
  • Simplified somehow the corresponding code, in particular: 1) removed obsolete flags "oldice". 2) removed flag "ibar": barycentric interpolation is used everywhere (except in start_init_subsurf, still calling grille_m - to be changed soon). 3) removed useless CPP_PHY precompilation directives, considering the possibility to run ce0l without physics is useless (ce0l is dedicated to Earth physics).
