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

1080	!! - In 'ocean only' case, non solar and solar ocean heat fluxes
1081	!! and total ocean freshwater fluxes
