|
o tools/genmake2: |
| 8 |
|
- comment out the "mpif.h" include in NetCDF test programm (for MPI built) |
| 9 |
|
since it's not necessary (and was preventing to use MNC in some cases). |
| 10 |
|
|
| 11 |
|
checkpoint64a (2012/11/16) |
| 12 |
|
o pkg/autodiff: |
| 13 |
|
- improve pkg-internal logical parameter switch (inAd/inFwd mode) so that |
| 14 |
|
autodiff_readparms.F no longer depends on calling order (within |
| 15 |
|
packages_readparms.F) and no longer requires to include ${PKG}_PARMS.h): |
| 16 |
|
rename param turnFreeDriftInAdMode to SEAICEuseFREEDRIFTswitchInAd |
| 17 |
|
and change param SEAICEuseDYNAMICSinAdMode to SEAICEuseDYNAMICSswitchInAd. |
| 18 |
|
o pkg/obcs: |
| 19 |
|
- adding tidal velocity forcing capability to obcs |
| 20 |
|
for usage example, see verification/seaice_obcs/input.tides |
| 21 |
|
o pkg/seaice: |
| 22 |
|
- turn the LSR-relaxation parameters WFAU/V into runtime parameters |
| 23 |
|
SEAICE_LSRrelaxU/V |
| 24 |
|
- introduce runtime parameter SEAICEetaZmethod (=0 by default) |
| 25 |
|
o pkg/aim_v23: |
| 26 |
|
- implement heating from friction (bottom friction and stratospheric drag). |
| 27 |
|
o pkg/shap_filt: |
| 28 |
|
- fix diagnostic "SHAP_dKE" (was 2 time smaller); implement heating from |
| 29 |
|
dissipation but only for Shap_funct=2, active when addFrictionHeating=T. |
| 30 |
|
o model/src: |
| 31 |
|
- move AddMass common block from DYNVARS.h to FFIELDS.h; allow to read-in |
| 32 |
|
time-constant addMass field from file (addMassFile); |
| 33 |
|
- support for heating due to friction (and Kinetic Energy dissipation): |
| 34 |
|
add option, run-time switch and 3-D field array + support code ; each pkg |
| 35 |
|
or S/R can add heating contribution (if there is a sink of KE); the sum is |
| 36 |
|
accounted for as a Temperature tendency term (EXTERNAL_FORCING_T). |
| 37 |
|
o pkg/seaice: |
| 38 |
|
- complete merge of ITD code into seaice_growth.F |
| 39 |
|
from MITgcm_contrib/torge/itd/code/ |
| 40 |
|
no verification so far, but Torge Martin tested |
| 41 |
|
"1-D test case and Beaufort set up; |
| 42 |
|
deliver okay results after 1 model year." |
| 43 |
|
- complete merge of SEAICE_SIZE.h into all relevant routines |
| 44 |
|
- move computation of eta at Z-points into calc_viscosities |
| 45 |
|
+ introduce global field etaZ |
| 46 |
|
+ add different methods for computing etaZ, for now the old |
| 47 |
|
method (simple averages of eta to Z-points) is hardwired |
| 48 |
|
+ replace etaMeanZ by etaZ in seaice_lsr, seaice_calc_residual, |
| 49 |
|
seaice_preconditioner |
| 50 |
|
- simplify computations for SEAICE_ZETA_SMOOTHREG |
| 51 |
|
- seaice_preconditioner: |
| 52 |
|
+ replace one remaining press by pressLoc (mistake) |
| 53 |
|
+ adjust printing of residuals |
| 54 |
|
- improve I/O of diagnostics of JFNK in seaice_jfnk.F: |
| 55 |
|
+ add (SEAICE.h) and rename some counters (initiliased in |
| 56 |
|
seaice_init_fixed.F) |
| 57 |
|
+ add _BEGIN/END_MASTER (myThid) around print statements |
| 58 |
|
+ print total number of iterations and failures over SEAICE_monFreq |
| 59 |
|
interval to STDOUT |
| 60 |
|
- move control over output-messages by fgmres to seaice_jfnk to save |
| 61 |
|
some operations |
| 62 |
|
- move resetting initial guess for fgmres outside of seaice_fgmres_driver |
| 63 |
|
in order to make restarts with sol .ne. zero (fgmres with restarts) |
| 64 |
|
(seaice_jfnk.F, seaice_fgmres.F) |
| 65 |
|
- seaice_calc_l/rhs.F: replace maskW/S by maskInW/S; this fixes |
| 66 |
|
a serious convergence problem when open boundaries are involved |
| 67 |
|
o pkg/ggl90: fix computation of control volumes for the case of |
| 68 |
|
ALLOW_GGL90_HORIZDIFF (probably not used very often): move control volumes |
| 69 |
|
up half a grid cell from C-centered to W-centered (pointed out by C. Eden) |
| 70 |
|
o pkg/seaice: simplify seaice_evp by avoiding use of extra fields u/vIceC |
| 71 |
|
o pkg/autodiff |
| 72 |
|
- Add inAdMode switch for SEAICEuseDYNAMICS: |
| 73 |
|
SEAICEuseDYNAMICSinAdMode |
| 74 |
|
(extend logic in ADAUTODIFF_INADMODE_SET) |
| 75 |
|
o pkg/seaice |
| 76 |
|
- Step 1 of merging ice-thickness distribution (ITD) code from |
| 77 |
|
MITgcm_contrib/torge/itd/ (author: Torge Martin) |
| 78 |
|
The code implements concept laid out in Thorndike et al. (1975); |
| 79 |
|
code is enabled via CPP flag SEAICE_ITD |
| 80 |
|
nITD (in SEAICE_SIZE.h) defines number of ice thickness categories; |
| 81 |
|
code is not complete yet!! |
| 82 |
|
- SEAICE_SIZE.h now included in almost all seaice routines |
| 83 |
|
o verification (using seaice): |
| 84 |
|
- switch back seaice-dynamics (+ lower SOLV_MAX_ITERS) in ADM exp. |
| 85 |
|
global_ocean.cs32x15.seaice ; update results. |
| 86 |
|
- compile B-grid dynamics in FW test exp 1D_ocean_ice_column ; |
| 87 |
|
- compile C-grid dynamics with #define SEAICE_ALLOW_JFNK in FW test exp |
| 88 |
|
offline_exf_seaice (previously compiling B-grid). |
| 89 |
|
o pkg/exf: |
| 90 |
|
- fix some STOP conditions in exf_check.F (from Aug 28, modifs did not allow |
| 91 |
|
to specify neither just 1 comp of wind or wind-stress, nor no surface momentum |
| 92 |
|
forcing): just replace CPP option ALLOW_ATM_WIND with run-time param useAtmWind. |
| 93 |
|
o pkg/layers (adjust changes from Sept 19): |
| 94 |
|
- do snap-shot output and fill diagnostics from inside iLa loop (layers_calc.F) |
| 95 |
|
this allows to remove "layers_maxNum" dimension from all layers arrays. |
| 96 |
|
o pkg/layers (adjust changes from Sept 19): |
| 97 |
|
- remove ALLOW_LAYERS_OUTPUT ; fix snap-shot and time-ave output ; |
| 98 |
|
- snap-shot extended to all type of layers (not just the 1rst type); |
| 99 |
|
- remove layers variables when corresponding CPP option is undef. |
| 100 |
|
o pkg/layers: |
| 101 |
|
- rename pkg/layers variable and add new output (layer exist & un-weighted |
| 102 |
|
velocity in layer) |
| 103 |
|
o pkg/seaice: |
| 104 |
|
- simplify (?) ocean-drag coefficent computations by using |
| 105 |
|
the same routine in all three solvers (saves some code lines) |
| 106 |
|
- remove global fields DRAGA and DRAGS from C-grid code and |
| 107 |
|
declare them locally in lsr.F (the only place where they are |
| 108 |
|
still used) |
| 109 |
|
- update AD output of lab_sea.evp (very sensitive anyway). |
| 110 |
|
o pkg/seaice: add Jacobian-free Newton Krylov solver for ice dynamics |
| 111 |
|
(Lemieux et al. 2010, 2012). Turn on with the usual SEAICE_ALLOW_JFNK |
| 112 |
|
and SEAICEuseJFNK=.true. A few things to note: |
| 113 |
|
- involves a FGMRES, that is parallel but very inefficient, |
| 114 |
|
because of many scalar products (global sums) in the Gram-Schmidt |
| 115 |
|
orthogonalization method. Needs to be replaced. Original code |
| 116 |
|
from J.-F. Lemieux |
| 117 |
|
- preconditioner for FGMRES is a stripped down version of LSOR |
| 118 |
|
- SOLV_MAX_ITERS is now used for LSOR as a solver and as a |
| 119 |
|
preconditioner. For the preconditioner, the default is set to 10. |
| 120 |
|
- Jacobian times vector is computed with finite differences |
| 121 |
|
- marginally related to JFNK-solver: add a smooth regularization for |
| 122 |
|
zeta with tanh that will improve convergence (Lemieux and Tremblay, |
| 123 |
|
2009) for any implicit solver (not implemented for EVP because EVP |
| 124 |
|
does not need this regularization in the first place). Define |
| 125 |
|
SEAICE_ZETA_SMOOTHREG in SEAICE_OPTIONS.h to use. |
| 126 |
|
o eesupp/src: |
| 127 |
|
- check in genmake2 that intrinsic S/R flush is available. |
| 128 |
|
- add S/R to flush IO unit (if intrinsic S/R flush is available) |
| 129 |
|
- flush standard & error msg unit before MPI termination |
| 130 |
|
- if debugMode, flush IO unit after printing msg |
| 131 |
|
o pkg/ctrl: |
| 132 |
|
- ctrl_unpack.F, ALLOW_GENARR3D_CONTROL code: fix missing argument in call |
| 133 |
|
to ctrl_set_unpack_xyz. |
| 134 |
|
|
| 135 |
