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.

Front page edition, cleaning in custom LaTeX commands and add index for single subfile compilation

  • Use \thanks storing cmd to refer to the ST members list for 2018 in an footnote on the cover page
  • NEMO and Fortran in small capitals
  • Removing of unused or underused custom cmds, move local cmds to their respective .tex file
  • Addition of new ones (\zstar, \ztilde, \sstar, \stilde, \ie, \eg, \fortran, \fninety)
  • Fonts for indexed items: italic font for files (modules and .nc files), preformat for code (CPP keys, routines names and namelists content)

    3535The alternative is to use diffusive schemes such as upstream or flux corrected schemes. 
    3636This last option was rejected because we prefer a complete handling of the model diffusion, 
    37 i.e. of the model physics rather than letting the advective scheme produces its own implicit diffusion without

    3939Note that in some very specific cases as passive tracer studies, the positivity of the advective scheme is required.

    283283In discrete form, all these properties are satisfied in $z$-coordinate (see Appendix C).

    297297As for the advective term, there is generally no strict conservation of mass even if,
