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

1083	!! - In 'ocean only' case, non solar and solar ocean heat fluxes
1084	!! and total ocean freshwater fluxes
