Changeset 2588 for LMDZ5/trunk/libf/dynphy_lonlat/phymar/iniphysiq_mod.F90

Timestamp:

Jul 13, 2016, 8:54:39 AM (8 years ago)

Author:

Message:

-Small change in the dynamics/physics interface organization:
externalize (from iniphysiq) operations wich initialize settings
common to all physics packages (e.g. global grid definitions;
in practice initializations for routines either in phy_common
or in dynphy_lonlat) in inigeomphy (located in dynphy_lonlat).
iniphysiq should only initialize settings in the corresponding
physics package (e.g. phylmd for dynphy_lonlat/phylmd/iniphysiq).

• Bug fix in phydev/iophy: is_south_pole_dyn replaces

is_south_pole since rev. 2429.
