[MITgcm-devel] llc with fewer than 5 faces

[Patrick Heimbach]

Hi Ian,

An is running fewer than 5 faces in her Arctic config.
She can do away with face #2, see here:
http://mitgcm.org/viewvc/MITgcm/MITgcm_contrib/atnguyen/llc_270/aste_270x450x180/input_ad/data.exch2
(in addition, she also uses faces of different sizes).
I reckon that’s what you might want to do also(?)

I know there must be a file that specifies how the faces are interconnected.  Would it simply be a matter of stripping out all references to faces 2 and 4 in that file, for example?
