[MITgcm-support] Too large of Sea Ice

[Dimitris Menemenlis]

I have same experience.
I even created a simplified set-up to demonstrate the issue:
https://github.com/MITgcm-contrib/llc_hires/tree/master/trillium/isomip

I suspect there may be a bug (or something problematic) in the
formulation of SHELFICEboundaryLayer
Can you try setting this to “.FALSE” and see what happens?
