|
o pkg/seaice: |
| 8 |
|
- bug fix in the evp solver: boundary conditions were affected be |
| 9 |
|
masking of zMax/zMin (changes results) |
| 10 |
|
- minor bug fix in boundary conditions in seaice_calc_strainrates |
| 11 |
|
(changes results for no_slip) |
| 12 |
|
- seaice_lsr.F: make interpolation of eta dependent on boundaries |
| 13 |
|
- replace hardcoded lower limit for zeta (zMin) by runtime parameter |
| 14 |
|
- add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean |
| 15 |
|
stress formulation and no-slip boundary conditions |
| 16 |
|
o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP |
| 17 |
|
in gad_calc_rhs.F ; add few safety stops in initialisation phase. |
| 18 |
|
o pkg/seaice: a first HSALT time stepping equation has been checked in |
| 19 |
|
o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV |
| 20 |
|
in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem |
| 21 |
|
without requiring DO-IF statements |
| 22 |
|
o pkg/thsice: |
| 23 |
|
use continuous power-law function for partition of energy between lateral |
| 24 |
|
melting/freezing and thinning/thickening ; old code using step function |
| 25 |
|
still available with #undef THSICE_FRACEN_POWERLAW |
| 26 |
|
update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice |
| 27 |
|
o testreport: change AD testing : check against results/output_adm.txt |
| 28 |
|
using same scripts as for forward test. |
| 29 |
|
|
| 30 |
|
checkpoint59g |
| 31 |
|
o adjoint testing: in preparation for changing testreport: |
| 32 |
|
- output format: cost and grad written on separated lines |
| 33 |
|
- ad output results in directory "results" (instead of "results_ad") |
| 34 |
|
o pkg/seaice: adding ice salinity HSALT as a prognostic variable |
| 35 |
|
o pkg/seaice: changes for using pkg/seaice with pkg/obcs |
| 36 |
|
o pkg/ecco: allow user defined cost function contributions |
| 37 |
|
o testreport: |
| 38 |
|
Allow to choose (per experiment) the list of tested output variables |
| 39 |
|
and the main variable (used to issue a pass/FAIL ) ; |
| 40 |
|
- for now, done by adding the specific list in file: [exp]/input/tr_checklist |
| 41 |
|
- default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ; |
| 42 |
|
Also modify printing of summary: |
| 43 |
|
a) ">" NN "<" indicates the "main" variable (used for pass/FAIL) |
| 44 |
|
b) echo the list of tested variables in the individual summary.txt of |
| 45 |
|
each experiment. |
| 46 |
|
o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of |
| 47 |
|
threads and number of processes (with #define GLOBAL_SUM_SEND_RECV) |
| 48 |
|
(but still depend on the tile decompostion of the domain). |
| 49 |
|
o pkg/seaice: change a discretization detail to make the B-grid code |
| 50 |
|
"more symmetric". This change is likely to remove all "ridges/leads" that |
| 51 |
|
where quasi-aligned with the grid in B-grid solutions. It may also be |
| 52 |
|
the solution to the stress coupling issues with the B-grid. |
| 53 |
|
o each tested exp: add a "run" directory with a standard ".cvsignore" file ; |
| 54 |
|
remove .cvsignore from input dir. (since testreport no longer run here). |
| 55 |
|
o pkg/thsice: |
| 56 |
|
- cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h" |
| 57 |
|
- fix reshaping of sea-ice just after advection: |
| 58 |
|
melt all the ice only if ice-volume is too small. |
| 59 |
|
- re-visit lateral/thinning repartition of melting (modifs from May 04, 2007): |
| 60 |
|
prevent lateral melting if sea-ice fraction is too close to iceMaskMin ; |
| 61 |
|
and update experiment global_ocean.cs32x15.icedyn (+start from pickup files). |
| 62 |
|
o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water |
| 63 |
|
tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged. |
| 64 |
|
o define mass2rUnit & rUnit2mass as units conversion factor, used for surface |
| 65 |
|
forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit |
| 66 |
|
(z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse; |
| 67 |
|
and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error |
| 68 |
|
of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16 |
| 69 |
|
-> update output.txt |
| 70 |
|
o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME): |
| 71 |
|
this affects truncation error: -> update output.txt of exp: |
| 72 |
|
global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr, |
| 73 |
|
ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon. |
| 74 |
