1047	!! ** Purpose : provide the stress over the ocean and, if no sea-ice,
1048	!! provide the ocean heat and freshwater fluxes.
1049	!!
1050	!! ** Method : - Receive all the atmospheric fields (stored in frcv array). called at each time step.
1051	!! OASIS controls if there is something do receive or not. nrcvinfo contains the info
1052	!! to know if the field was really received or not
1053	!!
1054	!! --> If ocean stress was really received:
1055	!!
1056	!! - transform the received ocean stress vector from the received
1057	!! referential and grid into an atmosphere-ocean stress in
1058	!! the (i,j) ocean referencial and at the ocean velocity point.
1059	!! The received stress are :
1060	!! - defined by 3 components (if cartesian coordinate)
1061	!! or by 2 components (if spherical)
1062	!! - oriented along geographical coordinate (if eastward-northward)
1063	!! or along the local grid coordinate (if local grid)
1064	!! - given at U- and V-point, resp. if received on 2 grids
1065	!! or at T-point if received on 1 grid
1066	!! Therefore and if necessary, they are successively
1067	!! processed in order to obtain them
1068	!! first as 2 components on the sphere
1069	!! second as 2 components oriented along the local grid
1070	!! third as 2 components on the U,V grid
1071	!!
1072	!! -->
1073	!!
1074	!! - In 'ocean only' case, non solar and solar ocean heat fluxes
1075	!! and total ocean freshwater fluxes
1076	!!
1077	!! ** Method : receive all fields from the atmosphere and transform
1078	!! them into ocean surface boundary condition fields

1080	!! ** Action : update utau, vtau ocean stress at U,V grid

1453	!! 'C'-grid : i- (j-) components given at U- (V-) point
1454	!! 'I'-grid : B-grid lower-left corner: both components given at I-point
1455	!!
1456	!! The received stress are :
1457	!! - defined by 3 components (if cartesian coordinate)

1459	!! - oriented along geographical coordinate (if eastward-northward)
1460	!! or along the local grid coordinate (if local grid)
1461	!! - given at U- and V-point, resp. if received on 2 grids
1462	!! or at a same point (T or I) if received on 1 grid
1463	!! Therefore and if necessary, they are successively
1464	!! processed in order to obtain them
