1054	!! ** Purpose : provide the stress over the ocean and, if no sea-ice,
1055	!! provide the ocean heat and freshwater fluxes.
1056	!!
1057	!! ** Method : - Receive all the atmospheric fields (stored in frcv array). called at each time step.
1058	!! OASIS controls if there is something do receive or not. nrcvinfo contains the info
1059	!! to know if the field was really received or not
1060	!!
1061	!! --> If ocean stress was really received:
1062	!!
1063	!! - transform the received ocean stress vector from the received
1064	!! referential and grid into an atmosphere-ocean stress in
1065	!! the (i,j) ocean referencial and at the ocean velocity point.
1066	!! The received stress are :
1067	!! - defined by 3 components (if cartesian coordinate)
1068	!! or by 2 components (if spherical)
1069	!! - oriented along geographical coordinate (if eastward-northward)
1070	!! or along the local grid coordinate (if local grid)
1071	!! - given at U- and V-point, resp. if received on 2 grids
1072	!! or at T-point if received on 1 grid
1073	!! Therefore and if necessary, they are successively
1074	!! processed in order to obtain them
1075	!! first as 2 components on the sphere
1076	!! second as 2 components oriented along the local grid
1077	!! third as 2 components on the U,V grid
1078	!!
1079	!! -->
1080	!!
1081	!! - In 'ocean only' case, non solar and solar ocean heat fluxes
1082	!! and total ocean freshwater fluxes
1083	!!
1084	!! ** Method : receive all fields from the atmosphere and transform
1085	!! them into ocean surface boundary condition fields

1087	!! ** Action : update utau, vtau ocean stress at U,V grid
