801	!! ** Purpose : provide the stress over the ocean and, if no sea-ice,
802	!! provide the ocean heat and freshwater fluxes.
803	!!
804	!! ** Method : - Receive all the atmospheric fields (stored in frcv array). called at each time step.
805	!! OASIS controls if there is something do receive or not. nrcvinfo contains the info
806	!! to know if the field was really received or not
807	!!
808	!! --> If ocean stress was really received:
809	!!
810	!! - transform the received ocean stress vector from the received
811	!! referential and grid into an atmosphere-ocean stress in
812	!! the (i,j) ocean referencial and at the ocean velocity point.
813	!! The received stress are :
814	!! - defined by 3 components (if cartesian coordinate)
815	!! or by 2 components (if spherical)
816	!! - oriented along geographical coordinate (if eastward-northward)
817	!! or along the local grid coordinate (if local grid)
818	!! - given at U- and V-point, resp. if received on 2 grids
819	!! or at T-point if received on 1 grid
820	!! Therefore and if necessary, they are successively
821	!! processed in order to obtain them
822	!! first as 2 components on the sphere
823	!! second as 2 components oriented along the local grid
824	!! third as 2 components on the U,V grid
825	!!
826	!! -->
827	!!
828	!! - In 'ocean only' case, non solar and solar ocean heat fluxes
829	!! and total ocean freshwater fluxes
830	!!
831	!! ** Method : receive all fields from the atmosphere and transform
