New URL for NEMO forge!   http://forge.nemo-ocean.eu

Since March 2022 along with NEMO 4.2 release, the code development moved to a self-hosted GitLab.
This present forge is now archived and remained online for history.

    132134for equatorial dynamics. The choice of the series of embedded ellipses (position of the foci and  
    133135variation of the ellipses) is a compromise between maintaining  the ratio of mesh anisotropy
