|
o mnc: add horizontal grid coordinates (XC,YC) and (XG,YG) to netcdf output |
| 8 |
|
for complex grids, for now only to "state", "adstate", "adexf", "adseaice" |
| 9 |
|
o model: add Christopher Wolfe's implemetation of the single reduction cg2d |
| 10 |
|
(d'Azevedo, Eijkhout, and Romine, 1999) with CPP-flag ALLOW_SRCG and |
| 11 |
|
runtime flag useSRCGSolver. Modify verification experiment global_with_exf |
| 12 |
|
to test this code |
| 13 |
|
o pkg/cd_code: |
| 14 |
|
Change defaut D-grid time-stepping to get the same for D-grid momentum as for |
| 15 |
|
C-grid momentum. D-grid velocity used to be stepped forward in time with |
| 16 |
|
Adams-Bashforth only on surface pressure term. Tests show that using AB on |
| 17 |
|
D-grid coriolis term improves stability (as expected from CD-scheme paper). |
| 18 |
|
To reproduce old results, add 2 options (in CD_CODE_OPTIONS.h). |
| 19 |
|
Update results of exp: global_with_exf (x2), ideal_2D_oce, isomip (x2), |
| 20 |
|
lab_sea (3 Fwd +3 AD), natl_box (x2), tutorial_global_oce_biogeo (Fwd+AD), |
| 21 |
|
tutorial_global_oce_latlon, tutorial_global_oce_optim & tutorial_tracer_adjsens. |
| 22 |
|
Keep old results by adding CD_CODE_OPTIONS.h in exp: cfc_example, exp2, |
| 23 |
|
lobal_ocean.90x40x15(+AD), global_ocean_ebm(+AD) and OpenAD. |
| 24 |
|
o pkg/obcs: |
| 25 |
|
- fix bug in initialisation (broken since Oct 1rst modification) |
| 26 |
|
for useOBCSprescribe without useEXF. |
| 27 |
|
|
| 28 |
|
checkpoint61y |
| 29 |
|
o pkg/seaice |
| 30 |
|
- change (once again) the discretization for the evp solver: rather than |
| 31 |
|
squaring the averages of strain rates, average the squares to give |
| 32 |
|
a better approximation to VP behavior (in simple test); this breaks |
| 33 |
|
verification experiments that use EVP (lab_sea and lab_sea.hb87) |
| 34 |
|
--> update outputs |
| 35 |
|
o add CPP-flag (in mom_calc_visc.F) and TAF directive (in gmredi_slope_limit) |
| 36 |
|
to improve vectorization of adjoint code on TARGET_NEC_SX |
| 37 |
|
o verification/vermix: |
| 38 |
|
- change vermix to a more "classical" 1d column with high vertical |
| 39 |
|
resolution, seasonal heat flux forcing and constant wind forcing |
| 40 |
|
--> update outputs |
| 41 |
|
o pkg/seaice |
| 42 |
|
- fix diagnostics of principal stress components for EVP |
| 43 |
|
- add optional diagnostics of non-linear convergence for LSOR solver |
| 44 |
|
- make maximum zeta a runtime parameter |
| 45 |
|
o model/src (3-d solver): |
| 46 |
|
Undo modif from Dec 12, 2005 (solve_for_pressure.F cvs version v.49), |
| 47 |
|
which consisted in removing the Surf. Non-Hydrostatic pressure from the |
| 48 |
|
whole column and adding it to Eta (inspired from Casualli, 1999): |
| 49 |
|
Only affects 3-D solver initial guess and only if using ExactConserv, |
| 50 |
|
but tests did show a degradation of solver convergence. For this reason, |
| 51 |
|
decide to disable this piece of code. |
| 52 |
|
to recover previous version, just set zeroPsNH = exactConserv (line 78). |
| 53 |
|
Update output of exp. global_ocean.cs32x15.viscA4 & hs94.cs-32x32x5.impIGW |
| 54 |
|
o pkg/ggl90: |
| 55 |
|
- fix previous modif (unfortunatly has not been documented here). |
| 56 |
o pkg/seaice/autodiff: |
