[MITgcm-support] Need assistance for tuning currents in the physical model

[Matthew Mazloff]

Hi Kunal

One option is to start by basing it on LLC4320, and evolve to your needs:
http://wwwcvs.mitgcm.org/viewvc/MITgcm/MITgcm_contrib/llc_hires/llc_4320/ <http://wwwcvs.mitgcm.org/viewvc/MITgcm/MITgcm_contrib/llc_hires/llc_4320/>

However, one difference is your SIZE.h would have
 &           OLx =   4,
 &           OLy =   4,
as you aren’t using cubed sphere or LLC
