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.

Last change on this file since 13141 was 13141, checked in by jchanut, 4 years ago
#2129, corrections/add ons to initial state interpolation with AGRIF 1) add namelist flag for child grid initial state interpolation - ice not considered yet 2) provide depths and not thicknesses as inputs to vertical linear interpolation 3) extend initial state interpolation to a restart scenario for parent grid (warning should be added in that case in order to prevent users doing this at each model restart...) The online interpolation seems to work fine in the VORTEX case (provided 0. is not considered as a special value in the initial velocity field, i.e. ln_spc_dyn=F)
