o pkg/seaice: |
| 8 |
|
Major overhaul of the LSOR solver: change discretization from original |
| 9 |
|
finite differences to finite volume. The old routine is still in the |
| 10 |
|
file seaice_lsr.F and can be turned on with the CPP-flag |
| 11 |
|
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 (except lab_sea//output_adm.txt |
| 43 |
|
which was left over, but fails at level 7 & 6) |
