1059	!! ** Purpose : provide the stress over the ocean and, if no sea-ice,
1060	!! provide the ocean heat and freshwater fluxes.
1061	!!
1062	!! ** Method : - Receive all the atmospheric fields (stored in frcv array). called at each time step.
1063	!! OASIS controls if there is something do receive or not. nrcvinfo contains the info
1064	!! to know if the field was really received or not
1065	!!
1066	!! --> If ocean stress was really received:
1067	!!
1068	!! - transform the received ocean stress vector from the received
1069	!! referential and grid into an atmosphere-ocean stress in
1070	!! the (i,j) ocean referencial and at the ocean velocity point.
1071	!! The received stress are :
1072	!! - defined by 3 components (if cartesian coordinate)
1073	!! or by 2 components (if spherical)
1074	!! - oriented along geographical coordinate (if eastward-northward)
1075	!! or along the local grid coordinate (if local grid)
1076	!! - given at U- and V-point, resp. if received on 2 grids
1077	!! or at T-point if received on 1 grid
1078	!! Therefore and if necessary, they are successively
1079	!! processed in order to obtain them
1080	!! first as 2 components on the sphere
1081	!! second as 2 components oriented along the local grid
1082	!! third as 2 components on the U,V grid
1083	!!
1084	!! -->
1085	!!
1086	!! - In 'ocean only' case, non solar and solar ocean heat fluxes
1087	!! and total ocean freshwater fluxes
1088	!!
1089	!! ** Method : receive all fields from the atmosphere and transform
1090	!! them into ocean surface boundary condition fields

1092	!! ** Action : update utau, vtau ocean stress at U,V grid
