	990	!! OASIS controls if there is something do receive or not. nrcvinfo contains the info
	991	!! to know if the field was really received or not
[888]	992	!!
[1218]	993	!! --> If ocean stress was really received:
[888]	994	!!
[1218]	995	!! - transform the received ocean stress vector from the received
	996	!! referential and grid into an atmosphere-ocean stress in
	997	!! the (i,j) ocean referencial and at the ocean velocity point.
	998	!! The received stress are :
	999	!! - defined by 3 components (if cartesian coordinate)
	1000	!! or by 2 components (if spherical)
	1001	!! - oriented along geographical coordinate (if eastward-northward)
	1002	!! or along the local grid coordinate (if local grid)
	1003	!! - given at U- and V-point, resp. if received on 2 grids
	1004	!! or at T-point if received on 1 grid
	1005	!! Therefore and if necessary, they are successively
	1006	!! processed in order to obtain them
	1007	!! first as 2 components on the sphere
	1008	!! second as 2 components oriented along the local grid

	1649	!! * solid precipitation (sprecip), used to add to qns_tot
[1218]	1650	!! the heat lost associated to melting solid precipitation
	1651	!! over the ocean fraction.
[6795]	1652	!! * heat content of rain, snow and evap can also be provided,
	1653	!! otherwise heat flux associated with these mass flux are
	1654	!! guessed (qemp_oce, qemp_ice)
[1218]	1655	!!
[6795]	1656	!! - the fluxes have been separated from the stress as
	1657	!! (a) they are updated at each ice time step compare to
	1658	!! an update at each coupled time step for the stress, and
	1659	!! (b) the conservative computation of the fluxes over the

	1661	!! after the ice advection and before the ice thermodynamics,
