[MITgcm-devel] recent shelfice_remeshing push

[Daniel Goldberg]

Hi Jean Michel

I have been looking through the recent commit for the shelfice_remeshing
P/R, and have a few questions, both regarding shelfice_init_varia.

1) I believe that in my P/R i had code under "IF (shelficeMassStepping)" to
reinitialise ro_surf to r_shelfice if a pickup is loaded. This is because
INIT_DEPTHS() is only called in INITIALISE_FIXED(), and so otherwise
ro_surf will not be updated, I don't think. Do you agree, and if so, was
this addressed elsewhere in your commit?

(also -- apologies if this code was not in my P/R. I had created a new
branch for horizontal remeshing off of the remeshing branch; and now that i
have removed my remeshing branch I am not sure if this change was
reflected.)

2) Current logic is to read from a pickup only if shelficeMassStepping is
turned on. But remeshing can occur even when Ice shelf mass does not
change, e.g. if initial hFac's are set as to trigger remeshing thresholds.
(One could argue that care should be taken in initialisation, but in
practice such situations could be difficult to avoid due to free surface
changes.) Would it be possible to read from the shelfice pickup whenever
remeshing is allowed?

Many thanks
Dan
