  • Resolution set to fixed
  • Status changed from new to closed

As for #2464, we took the opportunity of this bugfix to modify the way atm-ice stress is computed at U and V point.
We first compute it at T point and next distribute it over U and V point with a "masked" average.
With this method, we do the average of a product (rho*Cd*|Wnd|*Wnd) instead of the product of averaged values. We therefore keep a larger part of the signal with the new method.

fixed in [12926]. All sette tests are ok. As expected configuration with sea-ice and forcing are different: ORCA2_ICE_PISCES, ORCA2_SAS_ICE, AGRIF_DEMO and SPITZ12
