Martin, so 1-day time steps is OK for LSR?
Wouldn't it be safer to set SEAICE_deltaTdyn = 1200.,
consistent with deltaTmom instead of the default
SEAICE_deltaTdyn = deltaTtracer = 86400., ?

For these cases capping in a thermodynamically inconsistent way is a convenient way out (HEFF=MIN(HEFF,someMaxValue), but that’s not implementend anymore, is it?
