1041	!! ** Purpose : provide the stress over the ocean and, if no sea-ice,
1042	!! provide the ocean heat and freshwater fluxes.
1043	!!
1044	!! ** Method : - Receive all the atmospheric fields (stored in frcv array). called at each time step.
1045	!! OASIS controls if there is something do receive or not. nrcvinfo contains the info
1046	!! to know if the field was really received or not
1047	!!
1048	!! --> If ocean stress was really received:
1049	!!
1050	!! - transform the received ocean stress vector from the received
1051	!! referential and grid into an atmosphere-ocean stress in
1052	!! the (i,j) ocean referencial and at the ocean velocity point.
1053	!! The received stress are :
1054	!! - defined by 3 components (if cartesian coordinate)
1055	!! or by 2 components (if spherical)
1056	!! - oriented along geographical coordinate (if eastward-northward)
1057	!! or along the local grid coordinate (if local grid)
1058	!! - given at U- and V-point, resp. if received on 2 grids
1059	!! or at T-point if received on 1 grid
1060	!! Therefore and if necessary, they are successively
1061	!! processed in order to obtain them
1062	!! first as 2 components on the sphere
1063	!! second as 2 components oriented along the local grid
1064	!! third as 2 components on the U,V grid
1065	!!
1066	!! -->
1067	!!
1068	!! - In 'ocean only' case, non solar and solar ocean heat fluxes
1069	!! and total ocean freshwater fluxes
1070	!!
1071	!! ** Method : receive all fields from the atmosphere and transform
1072	!! them into ocean surface boundary condition fields

1074	!! ** Action : update utau, vtau ocean stress at U,V grid

1438	!! 'C'-grid : i- (j-) components given at U- (V-) point
1439	!! 'I'-grid : B-grid lower-left corner: both components given at I-point
1440	!!
1441	!! The received stress are :
1442	!! - defined by 3 components (if cartesian coordinate)

1444	!! - oriented along geographical coordinate (if eastward-northward)
1445	!! or along the local grid coordinate (if local grid)
1446	!! - given at U- and V-point, resp. if received on 2 grids
1447	!! or at a same point (T or I) if received on 1 grid
1448	!! Therefore and if necessary, they are successively
