Coupling two hemispheric SI³ with ocean via OASIS

The NEMO-SI³ configuration can already be split into two separated executables and coupled via OASIS. The resulting modularity helps to enhance computing performance.
In this new configuration, SI³ - in Stand Alone Surface module configuration - is split again into two independent models discretised on hemispheric grids. Details can be found here :

It is such a great idea to use the coupling to avoid the North Pole folding in sea-ice. So obvious… why we did not do it much earlier?
“twicefaster and two times cheaper than its single executable counterpart.” no need to say more… :grinning:
