948	!! ** Purpose : provide the stress over the ocean and, if no sea-ice,

950	!!
951	!! ** Method : - Receive all the atmospheric fields (stored in frcv array). called at each time step.
952	!! OASIS controls if there is something do receive or not. nrcvinfo contains the info
953	!! to know if the field was really received or not
954	!!
955	!! --> If ocean stress was really received:
956	!!
957	!! - transform the received ocean stress vector from the received
958	!! referential and grid into an atmosphere-ocean stress in
959	!! the (i,j) ocean referencial and at the ocean velocity point.
960	!! The received stress are :
961	!! - defined by 3 components (if cartesian coordinate)
962	!! or by 2 components (if spherical)
963	!! - oriented along geographical coordinate (if eastward-northward)
964	!! or along the local grid coordinate (if local grid)
965	!! - given at U- and V-point, resp. if received on 2 grids
966	!! or at T-point if received on 1 grid
967	!! Therefore and if necessary, they are successively
968	!! processed in order to obtain them
969	!! first as 2 components on the sphere
970	!! second as 2 components oriented along the local grid
971	!! third as 2 components on the U,V grid
972	!!
973	!! -->
974	!!
975	!! - In 'ocean only' case, non solar and solar ocean heat fluxes
976	!! and total ocean freshwater fluxes
977	!!
978	!! ** Method : receive all fields from the atmosphere and transform
