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