============================== |
============================== |

|
o Clean, new version of mom_calc_visc. Adds a new feature, viscAhRemax |
| 7 |
|
and viscA4Remax, which allow one to limit the minimum viscosity by specifying |
| 8 |
|
a maximum grid-scale Reynolds number. Also, changes all length calculations |
| 9 |
|
in the case of grid anisotropy to geometric mean of dx**2 and dy**2. |
| 10 |
|
Suggested values of viscosity parameters found in mom_calc_visc. |
| 11 |
|
Many new viscosity diagnostics available. |
| 12 |
|
|
| 13 |
|
checkpoint57s_post |
| 14 |
|
o Add clearing-house for viscosity calculations, mom_calc_visc and |
| 15 |
|
correct numerous bugs in LeithD and Smagorinsky discretizations. |
| 16 |
|
mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be |
| 17 |
|
used simultaneously, and to be used in mom_vecinv and mom_fluxform. |
| 18 |
|
Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F) |
| 19 |
|
and with Strain-Tension viscous term calculation (mom_hdissip.F). |
| 20 |
|
The Strain-Tension form is now called with useStrainTensonVisc=.true. |
| 21 |
|
ViscAhStrain and viscAhTension are now retired. |
| 22 |
|
o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4". |
| 23 |
|
o In response to JMC's bug report, genmake2 now ignores any soft-links |
| 24 |
|
that it finds in the *current* directory when searching for files. |
| 25 |
|
Soft-links found in any other source directories will still work as |
| 26 |
|
they did before. |
| 27 |
|
o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls |
| 28 |
|
a C routine to unlimit the stack size |
| 29 |
|
o mnc-ify pkg/aim snapshot vars |
| 30 |
|
o mnc-ify pkg/land as requested by Daniel |
| 31 |
|
o various changes to mnc including: |
| 32 |
|
- all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format |
| 33 |
|
- output can now be grouped so that all files within a group |
| 34 |
|
change the ITER portion of their names in lock-step together |
| 35 |
|
- can now read ("global") PER-FACE (in addition to PER-TILE) files |
| 36 |
|
and works with both EXCH1 and EXCH2 (but needs more testing) |
| 37 |
|
- writing works for all verification test cases w/ g77 on Linux |
| 38 |
|
|
| 39 |
|

| 44 |
|
o remove MINIMAL_TAVE_OUTPUT option ; |
| 45 |
|
add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT). |
| 46 |
|
o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src |
| 47 |
|
allows to compile without pkg/mdsio (& test successfully hs94.1x64x5) |
| 48 |
|
o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice) |
| 49 |
|
o add time-dependent SST, SSS control |

|
o cost_averages routines are modularized (new cost_averagesgeneric.F) |
| 52 |
|
o new infrastructure for seaice model vs. obs misfits in seaice/ |
| 53 |
|
* driver from the_main_loop.F is seaice_cost_driver.F |
| 54 |

checkpoint57q_post |
| 60 |
|
o fix initialisation Pb in calc_gw (get NANs in exp5 with g77) |
| 61 |
|

| 62 |
|
- bug was reported by Jean-Michel and Ian Fenty |
| 63 |
|
o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F) |
| 64 |
|
update exp. cpl_aim+ocn output. |
| 65 |
|
o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT |
| 66 |
|
Needed for high-res. runs with large global files |
| 67 |
|
to be able to limit tapelev size |
| 68 |
|
o Changed some tests for adjoint: |
| 69 |
|
* carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT |
| 70 |
|
* natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT |
| 71 |
|
* global_ocean.90x40x15/ back to default 3-level checkpointing |
| 72 |
|
o Modifications to enable scripted COMMON to MODULE conversion |
| 73 |
|
* verification/OpenAD/code/ has necessary scripts and description; |
| 74 |
|
* converts, compiles and runs successfully; |
| 75 |
|
|
| 76 |
|
checkpoint57p_post |
| 77 |
|
o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F |
| 78 |
|
o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED |
| 79 |
|
(already the case for some pkgs, including recent MNC_init, e.g. thsice) |
| 80 |
|
o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP) |
| 81 |
|
o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F |
| 82 |
|
(was already the case for dissipation with mom_vecinv, |
| 83 |
|
and also the case for grad.PhiHyd when staggered-timeStep) |
| 84 |
|
This will allow to put dissipation out-off the AB time-stepping. |
| 85 |
|
Unfortunately, affects truncation error. Update output of exp. that "fails" |
| 86 |
|
(cg2d matching number) and leave the others for later: front_relax(10), |
| 87 |
|
global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12), |
| 88 |
|
matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2). |

| 114 |
|
|
| 115 |
|
checkpoint57m_post |
| 116 |
|
o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into) |
| 117 |
|
and advect_cs (use EXCH-2 and standard cs-32 grid files). |
| 118 |
|
o pkg/exch2: filling of face-corner halo regions is optional |
| 119 |
|
(ifdef W2_FILL_NULL_REGIONS) and is turned off by default. |
| 120 |
|
|

| 166 |
|
|
| 167 |
|
checkpoint57i_post |
