o experiment fizhi-cs-aqualev20: |
| 8 |
|
switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE) |
| 9 |
|
and generate new output. Note: new output is much closer to the old |
| 10 |
|
one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from |
| 11 |
|
the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007. |
| 12 |
|
o pkg/fizhi: |
| 13 |
|
- change to avoid indices going deliberately over array-bounds |
| 14 |
|
- remove unnecessary MPI stuff |
| 15 |
|
- perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY" |
| 16 |
|
- new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE: |
| 17 |
|
does not go over array-bounds and therefore returns reliable output. |
| 18 |
|
- in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls: |
| 19 |
|
this S/R has 4 output arguments, which are used inside "get_alarm"; |
| 20 |
|
when it is called with the same variable "ndum" in place of several |
| 21 |
|
output arguments, this produces weird side effect inside "get_alarm" |
| 22 |
|
(e.g., datein=dates(n) is overwritten by timein=times(n) since both |
| 23 |
|
datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum" |
| 24 |
|
address) and produces error. |
| 25 |
|
o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output |
| 26 |
|
o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F: |
| 27 |
|
update lab_sea.lsr & lab_sea.salt_plume results |
| 28 |
|
o pkg/seaice: |
| 29 |
|
Major overhaul of the LSOR solver: change discretization from original |
| 30 |
|
finite differences to finite volume. The old routine is still in the |
| 31 |
|
file seaice_lsr.F and can be turned on with the CPP-flag |
| 32 |
|
SEAICE_OLD_AND_BAD_DISCRETIZATION |
| 33 |
|
Along with this change, the discretization of the strain rates is changed. |
| 34 |
|
The same flag turns on the old discretization in seaice_calc_strainrates.F |
| 35 |
|
All verification experiments with seaice are affected (except for |
| 36 |
|
seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old |
| 37 |
|
results by setting the above flag. |
| 38 |
|
Further changes involve changes in defaults: |
| 39 |
|
- ALLOW_FLOODING is defined and turned on by default |
| 40 |
|
- SEAICE_advSnow = .true. is now the default |
| 41 |
|
- SEAICE_advSalt = .true. is now the default |
| 42 |
|
- SEAICE_advAge = .true. is now the default |
| 43 |
|
- SEAICE_clipVelocities = .false. is now the default |
| 44 |
|
(as per J. Zhang's recommendation) |
| 45 |
|
- B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE |
| 46 |
|
is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS |
| 47 |
|
- seaice_growth: replace computation of UG by a simple copy from wspeed |
| 48 |
|

o pkg/seaice: a few bug fixes mostly concerning the metric terms: |
| 51 |
|
seaice_lsr: fixed a few metric terms, |
| 52 |
|
affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs |
| 53 |
|
add more debugging diagnostics |
| 54 |
|
seaice_evp: removed superfluous many metric terms of FV discretization |
| 55 |
|
of stress divergence |
| 56 |
|
affects lab_sea, lab_sea.hb87 |
| 57 |
|
seaice_ocean_stress: removed superfluous many metric terms of FV discretization |
| 58 |
|
of stress divergence for non-evp solver |
| 59 |
|
(this part is not tested anywhere) |
| 60 |
|
seaice_calc_strainrates: fixed a bug in no-slip boundary conditions, |
| 61 |
|
they were effectively only half slip |
| 62 |
|
affects lab_sea.hb87 |
| 63 |
|
updated all relevant verification experiments (except lab_sea//output_adm.txt |
| 64 |
|
which was left over, but fails at level 7 & 6) |
| 65 |
|
|
| 66 |
|
checkpoint61j |
| 67 |
|
o pkg/seaice: turn a few hard wired parameters into run time parameters |
| 68 |
|
o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model |
| 69 |
|
time in seconds as promised by the usints in seaice_monitor and exf_monitor |
| 70 |
o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids |
o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids |
| 71 |
that are not cubed-sphere grids |

| 72 |
o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR |
