798	!! ** Purpose : provide the stress over the ocean and, if no sea-ice,
799	!! provide the ocean heat and freshwater fluxes.
800	!!
801	!! ** Method : - Receive all the atmospheric fields (stored in frcv array). called at each time step.
802	!! OASIS controls if there is something do receive or not. nrcvinfo contains the info
803	!! to know if the field was really received or not
804	!!
805	!! --> If ocean stress was really received:
806	!!
807	!! - transform the received ocean stress vector from the received
808	!! referential and grid into an atmosphere-ocean stress in
809	!! the (i,j) ocean referencial and at the ocean velocity point.
810	!! The received stress are :
811	!! - defined by 3 components (if cartesian coordinate)
812	!! or by 2 components (if spherical)
813	!! - oriented along geographical coordinate (if eastward-northward)
814	!! or along the local grid coordinate (if local grid)
815	!! - given at U- and V-point, resp. if received on 2 grids
816	!! or at T-point if received on 1 grid
817	!! Therefore and if necessary, they are successively
818	!! processed in order to obtain them
819	!! first as 2 components on the sphere
820	!! second as 2 components oriented along the local grid
821	!! third as 2 components on the U,V grid
822	!!
823	!! -->
824	!!
825	!! - In 'ocean only' case, non solar and solar ocean heat fluxes
826	!! and total ocean freshwater fluxes
827	!!
828	!! ** Method : receive all fields from the atmosphere and transform
