o Redefine viscC?Leith*. Change the coefficients of Leith viscosity |
| 8 |
|
to be proportional to enstrophy dissipation length. Thus, |
| 9 |
|
viscC?leith?_new=pi*(viscC?leith?_old)^(1/3) |
| 10 |
|
This is now consistent with Smagorinsky and with the manual. |

|
o OBCS and PTRACERS: add open boundary support for passive tracers |
| 14 |
|
- either use homogenous (pseudo) v.Neumann conditions or prescribe |
| 15 |
|
OB-values from file; this is not different from the way theta and salinity |
| 16 |
|
are treated |
| 17 |
|
- however, Orlanski-radiation conditions are not supported, and the model |
| 18 |
|
will stop if you use pTracers and Orlanski at the same time. |
| 19 |
|
- beefed up the rountine obcs_external_fields_load: now only those open |
| 20 |
|
boundary values are overwritten with values from files for which there |
| 21 |
|
are really files, otherwise the OB-fields remain untouched. This makes |
| 22 |
|
it possible to use different OBs at different ends of the domain (as |
| 23 |
|
with EXF) |
| 24 |
|
o reduce number of exch calls in shap_filt (s2). |
| 25 |
|
o CS-grid: fix divergence contribution to Leith viscosity. Affects (@ |
| 26 |
|
truncation level) 4/5 MLAdjust test results (11&12 digits match). |
| 27 |
|
|

|
o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4 |
| 30 |
|
o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get |
| 31 |
|
same truncation, independent of the face number: affects affects several |
| 32 |
|
test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5). |
| 33 |
|
o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times); |
| 34 |
|
note that biharmonic viscosity + no-slip was not tested in any experiment. |
| 35 |
|
o fix bug in non-linear free-surf side-drag ; generate new output for |
| 36 |
|
global_ocean.cs32x15(+.thsice) & global_ocean_pressure. |
| 37 |
|
o make mnc honor the writeBinaryPrec flag for most kinds of output |
| 38 |
|
o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum |
| 39 |
|
o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation |
| 40 |
|
error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5). |
| 41 |
|
o add brackets in multi-terms sum to get same truncation, independent of |
| 42 |
|
the face number (manage to get exactly same value of gU,gV at the cs-edge) |
| 43 |
|
affects several test. exp. Update global_ocean.cs32x15 (+.thsice). |
| 44 |
|
o Clean, new version of mom_calc_visc. Adds a new feature, viscAhRemax |
| 45 |
|
and viscA4Remax, which allow one to limit the minimum viscosity by specifying |
| 46 |
|
a maximum grid-scale Reynolds number. Also, changes all length calculations |
| 47 |
|
in the case of grid anisotropy to geometric mean of dx**2 and dy**2. |
| 48 |
|
Suggested values of viscosity parameters found in mom_calc_visc. |
| 49 |
|
Many new viscosity diagnostics available. |

| 52 |
|
o Add clearing-house for viscosity calculations, mom_calc_visc and |
| 53 |
|
correct numerous bugs in LeithD and Smagorinsky discretizations. |
| 54 |
|
mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be |
| 55 |
|
used simultaneously, and to be used in mom_vecinv and mom_fluxform. |
| 56 |
|
Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F) |
| 57 |
|
and with Strain-Tension viscous term calculation (mom_hdissip.F). |
| 58 |
|
The Strain-Tension form is now called with useStrainTensonVisc=.true. |
| 59 |
|
ViscAhStrain and viscAhTension are now retired. |
| 60 |
|
o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4". |
| 61 |
|
o In response to JMC's bug report, genmake2 now ignores any soft-links |
| 62 |
|
that it finds in the *current* directory when searching for files. |
| 63 |
|
Soft-links found in any other source directories will still work as |
| 64 |
|
they did before. |
| 65 |
|
o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls |
| 66 |
|
a C routine to unlimit the stack size |
| 67 |
|
o mnc-ify pkg/aim snapshot vars |
| 68 |
|
o mnc-ify pkg/land as requested by Daniel |
| 69 |
|
o various changes to mnc including: |
| 70 |
|
- all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format |
| 71 |
|
- output can now be grouped so that all files within a group |
| 72 |
|
change the ITER portion of their names in lock-step together |
| 73 |
|
- can now read ("global") PER-FACE (in addition to PER-TILE) files |
| 74 |
|
and works with both EXCH1 and EXCH2 (but needs more testing) |
| 75 |
|
- writing works for all verification test cases w/ g77 on Linux |
| 76 |
|
|
