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.

The feasibility study related to the introduction of the  PETSc library  has been concluded. From this study it has been deduced  that a  consistent manpower is needed. Since this effort is not  available using  the currently funded projects, the activity related to  the introduction  of PETSc into the NEMO code will be sustained when new  project funds  will be achieved.
