[MITgcm-support] Can I find the code of the N-S equations?

[Jody Klymak]

Hi Jing,

Sorry, I misspelled http://dx.doi.org/10.1016/j.ocemod.2011.07.002 Vitousek and Fringer.

You need non-hydrostatic because the KdV equation is the balance between the non linear steepening term and the dispersion term, and you don't get the right dispersion if you don't have non-hydrostatic.

Cheers,  Jody
