[MITgcm-support] Ice not Moving when Resolution is Very High

Hey Nils,
thanks for the reply-- I believe your thesis may be useful regardless.
However, and perhaps I should have been clearer in my first message, the
floe I initialize should indeed be in free drift. It is an ice floe of size
25x18 grid cells, located in the centre of a 192x88 cell domain such that
it doesn't touch any of the walls.
I've attached some movies showing my cases at 500m and 1km resolutions so
you can see what I mean. The time format at the top is days:hours:minutes.
Both cases are using constant windspeed of 6 m/s.
At resolutions higher than ~500m (not an exact bound, just an estimate) no
motion is visible.
Note how in the 500m case the right bound of the initial floe remains
static at A=1 even though ice moves past/off of it in much lower
concentration. I'm not sure what to make of that but perhaps it's some clue.
Regards and thanks,
Senja
