4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/obcs:
8     - fix bug in initialisation (broken since Oct 1rst modification)
9       for useOBCSprescribe without useEXF.
10    
11    checkpoint61y
12    o pkg/seaice
13     - change (once again) the discretization for the evp solver: rather than
14       squaring the averages of strain rates, average the squares to give
15       a better approximation to VP behavior (in simple test); this breaks
16       verification experiments that use EVP (lab_sea and lab_sea.hb87)
17        --> update outputs
18    o add CPP-flag (in mom_calc_visc.F) and TAF directive (in gmredi_slope_limit)
19      to improve vectorization of adjoint code on TARGET_NEC_SX
20    o verification/vermix:
21      - change vermix to a more "classical" 1d column with high vertical
22        resolution, seasonal heat flux forcing and constant wind forcing
23        --> update outputs
24    o pkg/seaice
25     - fix diagnostics of principal stress components for EVP
26     - add optional diagnostics of non-linear convergence for LSOR solver
27     - make maximum zeta a runtime parameter
28    o model/src (3-d solver):
29      Undo modif from Dec 12, 2005 (solve_for_pressure.F cvs version v.49),
30       which consisted in removing the Surf. Non-Hydrostatic pressure from the
31       whole column and adding it to Eta (inspired from Casualli, 1999):
32       Only affects 3-D solver initial guess and only if using ExactConserv,
33       but tests did show a degradation of solver convergence. For this reason,
34       decide to disable this piece of code.
35       to recover previous version, just set zeroPsNH = exactConserv (line 78).
36      Update output of exp. global_ocean.cs32x15.viscA4 & hs94.cs-32x32x5.impIGW
37    o pkg/ggl90:
38     - fix previous modif (unfortunatly has not been documented here).
39  o pkg/seaice/autodiff:  o pkg/seaice/autodiff:

43   - modify computation and store zetaC/Z in seaice_evp for TAF   - modify computation and store zetaC/Z in seaice_evp for TAF
44   - add CPP-flag SEAICE_ALLOW_CLIPVELS (undefined by default)   - add CPP-flag SEAICE_ALLOW_CLIPVELS (undefined by default)
45   - change seaice_calc_viscosities/strainraties for better   - change seaice_calc_viscosities/strainrates for better
