[MITgcm-support] picking ivdc_kappa

Hello

Is there a rule of thumb (or something more systematic) for picking
the implicit diffusivity (ivdc_kappa) used for convective adjustment?
FYI: my vertical grid spacing is 100 m and I am currently using 100 m^2/s.
(With a time step of 3600 sec, this would of course be unstable with an
explicit scheme.)

Thanks, Samar
