[MITgcm-support] rStar with cavities

[Martin Losch]

Hi Kaitlin,

I think they should work together. 
I have once (in the very beginning of this in 2006 or so) tried to use the rStar coordinates as surface (topography) following coordinates for better near surface resolution in the cavities, but because we don’t have a decent formulation for the pressure gradient for the case of strongly sloping vertical layer interfaces, this leads to too much pressure gradient error.

I ran with and without rStar and can see some non-negligible differences in the cavity, which is a bit concerning. Is it confirmed whether or not they work together?
