[MITgcm-devel] initialisation and mnc

[Patrick Heimbach]

Hi there,

indeed, probably one of the main reasons for having
a pkg_init_fixed.F and a pkg_init_varia.F
is to put all non-AD relevant (fixed) stuff in the
former and easily hide it from TAF.
Array initialisations are active and would be in 
pkg_init_varia.F
So I'd agree with both Jean-Michel's points.

At some distant point we may try out to also
include all fixed init. into the AD-related part.
TAF should, in principle figure out what is needed
and what's not. But since there's still a wide gap
between what ought to work in principle and what does,
that's not a useful exercise right now.
Some of this will be relevant for the bottom
topography control.
