    9696=== New reference configuration with AGRIF: AGRIF_DEMO

    98 {{{#!td 
    99 AGRIF_DEMO is based on the [wiki:Users/ReferenceConfigurations/ORCA2_LIM3_PISCES] global 2° configuration but it includes 3 online nested grids that demonstrate the overall capabilities of AGRIF in a realistic context, including nesting sea ice models.  \\ 
    100 The configuration includes a 1:1 grid in the Pacific and two successively nested grids with odd and even refinement ratios over the Arctic ocean. The finest grid spanning the whole Svalbard archipelago is of particular interest to check that sea ice coupling is done properly. The 1:1 grid, used alone, is used as a benchmark to check that the solution is not corrupted by grid exchanges. \\

    101111Note that since grids interact only at the baroclinic time level, numerically exact results can not be achieved in the 1:1 case. One has to switch to a fully explicit in place of a split explicit free surface scheme in order to retrieve perfect reproducibility.
