|
o model/src: |
8 |
|
- re-arrange extrapolation calculation in Adams-Bashforth S/R (affects machine |
9 |
|
truncation) and add diagnostics for Adams-Bashforth tendency increment. |
10 |
|
- update test-exp. AD output: |
11 |
|
1D_ocean_ice_column, bottom_ctrl_5x5, lab_sea.noseaicedyn, obcs_ctrl; |
12 |
|
and FWD output: exp4 (x3), fizhi-cs-32x32x40, fizhi-cs-aqualev20, |
13 |
|
front_relax (x3), global_ocean.90x40x15 (x2), global_ocean.cs32x15 (x5), |
14 |
|
global_ocean_ebm, ideal_2D_oce, internal_wave, isomip (x3), lab_sea (x4), |
15 |
|
matrix_example, MLAdjust (x5), natl_box (x2), tutorial_advection_in_gyre, |
16 |
|
tutorial_global_oce_in_p, tutorial_global_oce_latlon and |
17 |
|
tutorial_plume_on_slope. |
18 |
|
o pkg/diagnostics/diagstats_calc.F: add special code for TARGET_NEC_SX |
19 |
|
that vectorises. This code uses 3 extra 2D fields, F90 array assignments |
20 |
|
and F90 intrinsic routines SUM, MINVAL, MAXVAL, but since TARGET_NEC_SX |
21 |
|
does not even come with an F77 compiler anymore, this should not be |
22 |
|
a limitation |
23 |
|
|
24 |
|
checkpoint63e (2011/11/06) |
25 |
|
o pkg/seaice adjoint of LSR: |
26 |
|
- substantially rework STORE dirs. |
27 |
|
- add new flag SEAICE_LSR_ADJOINT_ITER and parameter SOLV_MAX_FIXED |
28 |
|
this flag will do SOLV_MAX_ITERS but only store SOLV_MAX_FIXED fields |
29 |
|
and only perform SOLV_MAX_FIXED adjoint iters. |
30 |
|
If flag SEAICE_LSR_ADJOINT_ITER is undef-ined, the store in the iteration |
31 |
|
always goes to same record, meaning that the last forward field will be |
32 |
|
the one used in the adjoint - an approximation. |
33 |
|
- now produces non-zero LSR-related gradients, and acceptable gradients for |
34 |
|
An's zonal (x-z) test case (to be checked in) |
35 |
|
- lab_sea: produces acceptable gradients for lab_sea with forward/backward LSR |
36 |
|
(but these are screwed up by the thermodynamics in the first place); |
37 |
|
reduce from 4 to 3 timesteps to avoid t.d. issue as temporary solution; |
38 |
|
output_adm.txt also reflects changes to seaice_lsr |
39 |
|
- global_ocean.cs32x15: |
40 |
|
* the "default" input_ad.seaice has been re-defined to always exclude dynamics |
41 |
|
(output_adm.seaice.txt was updated) |
42 |
|
* new input_ad.seaice_dynmix tests a forward LSR / backward free-drift |
43 |
|
(output_adm.seaice_dynmix.txt) |
44 |
|
o test-exp. exp4+stevens: |
45 |
|
- switch off pTracers and nonHydrostatic (restart problems with NH); update output |
46 |
|
o pkg/seaice (lsr solver): |
47 |
|
- put coriolis term into FORCEX,Y (as in seaice_evp.F; previously in rhsU,V only); |
48 |
|
update output (change truncation) of FWD test exp lab_sea & global_ocean.cs32x15 |
49 |
|
- fix SEAICEuseFREEDRIFT for new OBCS version (ndef OBCS_UVICE_OLD) |
50 |
|
- new parameter "LSR_mixIniGuess" allows (if=2,4) to mix free-drift solution |
51 |
|
into initial guess for linearised solver; use weight ~ (1/err)^2,4. |
52 |
|
- compute (with new S/R) and print initial (+ free-driff sol. if available) |
53 |
|
and final residual of linearised system. |
54 |
|
o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity |
55 |
|
(requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F) |
56 |
|
o pkg/obcs: Stevens BCs (still only for east and west) |
57 |
|
- fix Stevens BCs by using intermediate velocities of previous |
58 |
|
time step as "baroclinic" contribution rather velocity of one grid cell |
59 |
|
inside the boundaries; more consistent but makes the entire treatment |
60 |
|
more complicated, requires new pickup files and two new S/Rs: |
61 |
|
obcs_copy_uv_n and obcs_save_uv_n |
62 |
|
keep old version with flag OBCS_STEVENS_USE_INTERIOR_VELOCITY |
63 |
|
(undefined by default) |
64 |
|
- silently move computation of some grid factors into separate loops to |
65 |
|
save some recomputations |
66 |
|
- add a hack for non-linear free surface |
67 |
|
- add a verification experiment to exp4 that tests this code |
68 |
o make gluemnc/xplodemnc work with (moron) non-GNU shell tools |
