o model/src/ini_curvilinear_grid.F: check in hack for SX8 compiler |
o pkg/seaice: |

Major overhaul of the LSOR solver: change discretization from original |

have a proper exchange for them. Most compilers do not seem |
finite differences to finite volume. The old routine is still in the |
| 10 |
to mind divisions by zero in the overlaps, as long as the results are |
file seaice_lsr.F and can be turned on with the CPP-flag |
| 11 |
not used anywhere, but sxf90 does. |
SEAICE_OLD_AND_BAD_DISCRETIZATION |
| 12 |
|
Along with this change, the discretization of the strain rates is changed. |
| 13 |
|
The same flag turns on the old discretization in seaice_calc_strainrates.F |
| 14 |
|
All verification experiments with seaice are affected (except for |
| 15 |
|
seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old |
| 16 |
|
results by setting the above flag. |
| 17 |
|
Further changes involve changes in defaults: |
| 18 |
|
- ALLOW_FLOODING is defined and turned on by default |
| 19 |
|
- SEAICE_advSnow = .true. is now the default |
| 20 |
|
- SEAICE_advSalt = .true. is now the default |
| 21 |
|
- SEAICE_advAge = .true. is now the default |
| 22 |
|
- SEAICE_clipVelocities = .false. is now the default |
| 23 |
|
(as per J. Zhang's recommendation) |
| 24 |
|
- B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE |
| 25 |
|
is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS |
| 26 |
|
- seaice_growth: replace computation of UG by a simple copy from wspeed |
| 27 |

o pkg/seaice: a few bug fixes mostly concerning the metric terms: |
| 30 |
|
seaice_lsr: fixed a few metric terms, |
| 31 |
|
affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs |
| 32 |
|
add more debugging diagnostics |
| 33 |
|
seaice_evp: removed superfluous many metric terms of FV discretization |
| 34 |
|
of stress divergence |
| 35 |
|
affects lab_sea, lab_sea.hb87 |
| 36 |
|
seaice_ocean_stress: removed superfluous many metric terms of FV discretization |
| 37 |
|
of stress divergence for non-evp solver |
| 38 |
|
(this part is not tested anywhere) |
| 39 |
|
seaice_calc_strainrates: fixed a bug in no-slip boundary conditions, |
| 40 |
|
they were effectively only half slip |
| 41 |
|
affects lab_sea.hb87 |
| 42 |
|
updated all relevant verification experiments |
| 43 |
|

|
checkpoint61j |
| 45 |
|
o pkg/seaice: turn a few hard wired parameters into run time parameters |
| 46 |
|
o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model |
| 47 |
|
time in seconds as promised by the usints in seaice_monitor and exf_monitor |
| 48 |
|
o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids |
| 49 |
|
that are not cubed-sphere grids |
| 50 |
|
o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR |
| 51 |
|
o pkg/ctrl: |
| 52 |
|
fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low) |
| 53 |
|
o non-hydrostatic (calc_gw.F): |
| 54 |
|
fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec |
| 55 |
|
update output of exp. global_ocean.cs32x15.viscA4 |
| 56 |
|
o remove backward compatibility for thetaMin,phiMin |
| 57 |
|
(replaced by xgOrigin,ygOrigin on Jan 27, 2009) |
| 58 |
|
o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the |
| 59 |
|
interpolated wind field not only for curvilineargrid=.true., but also |
| 60 |
|
for a rotated grid (rotateGrid=.true.) |
| 61 |
|
o pkg/exf: add capability to bypass interpolation for runoff |
| 62 |
|
by setting yet another CPP-flag |
| 63 |
|
o eesupp/src, B-grid exchange: |
| 64 |
|
add simple (6 tiles, non MPI) CS exch + standard interface S/R. |
| 65 |
|
o autodiff |
| 66 |
|
new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV |
| 67 |
|
allows to switch to single-prec common blocks; |
| 68 |
|
corresponding switch occurs in tamc.h, integer isbyte |
| 69 |
|
TAF store directivs "byte" and "kind" seem equivalent; |
| 70 |
|
Most tamc.h have been updated correspondingly. |
| 71 |
|
|

| 73 |
|
o autodiff: |
| 74 |
|
fix autodiff_sore/_restore indices for obcs |
| 75 |
|
(spotted by I. Hoteit, M. Mazloff) |
| 76 |
|
o pkg/autodiff, pkg/ctrl: |
| 77 |
|
Add flag to reduce all tapelev I/O to single-prec. |
| 78 |
|
In data.ctrl set |
| 79 |
|
doSinglePrecTapelev = .TRUE. |
| 80 |
|
o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2: |
| 81 |
|
check in hack for SX8 compiler (for dxV, dyU); remove it afterwards. |
| 82 |
