1075	!! ** Purpose : provide the stress over the ocean and, if no sea-ice,
1076	!! provide the ocean heat and freshwater fluxes.
1077	!!
1078	!! ** Method : - Receive all the atmospheric fields (stored in frcv array). called at each time step.
1079	!! OASIS controls if there is something do receive or not. nrcvinfo contains the info
1080	!! to know if the field was really received or not
1081	!!
1082	!! --> If ocean stress was really received:
1083	!!
1084	!! - transform the received ocean stress vector from the received
1085	!! referential and grid into an atmosphere-ocean stress in
1086	!! the (i,j) ocean referencial and at the ocean velocity point.
1087	!! The received stress are :
1088	!! - defined by 3 components (if cartesian coordinate)
1089	!! or by 2 components (if spherical)
1090	!! - oriented along geographical coordinate (if eastward-northward)
1091	!! or along the local grid coordinate (if local grid)
1092	!! - given at U- and V-point, resp. if received on 2 grids
1093	!! or at T-point if received on 1 grid
1094	!! Therefore and if necessary, they are successively
1095	!! processed in order to obtain them
1096	!! first as 2 components on the sphere
1097	!! second as 2 components oriented along the local grid
1098	!! third as 2 components on the U,V grid
1099	!!
1100	!! -->
1101	!!
1102	!! - In 'ocean only' case, non solar and solar ocean heat fluxes
1103	!! and total ocean freshwater fluxes
1104	!!
1105	!! ** Method : receive all fields from the atmosphere and transform
