[MITgcm-support] Banding, Checkerboarding in KPP Viscosities

[Michael Schaferkotter]

if you have not done so, have a read of

“kpp blues” and the related thread that follows that thread.

a few years ago, i dealt with checkerboarding by adjusting the biharmonic viscosity.
don/t know if that applies here though.
