|
o non-hydrostatic code |
| 7 |
|
- added horizontal viscosity parameter viscAhW for w, that replaces viscAh |
| 8 |
|
in calc_gw.F |
| 9 |
|
- defaults to viscAh |
| 10 |
|
- this is useful, when I want to use viscAh=0 (e.g., only biharmonic |
| 11 |
|
friction or Leith) in non-hydrostatic mode, as long as there is |
| 12 |
|
no biharmonic friction and/or Leigth or equivalent for vertical velocity. |
| 13 |
|
o pkg/cost |
| 14 |
|
extend simple cost functions to treat time mean quantities |
| 15 |
|
(T,U,V) via cost_accumulate_state from cost_tile |
| 16 |
|
o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to |
| 17 |
|
be 2 times larger than the minimum size the advection scheme requires. |
| 18 |
|
now get a perfect conservation of salt in advect_cs test-exp (updated) |
| 19 |
|
o GGL90 (Gaspar's TKE mixed layer) |
| 20 |
|
- add horizontal diffusion of TKE, requires exchanges in |
| 21 |
|
do_fields_blocking_exchanges, horizontal diffusivity is zero by |
| 22 |
|
default. In OPA there is no horizontal diffusion of TKE but the |
| 23 |
|
mixing coefficients are computed from a horizontal average of TKE of |
| 24 |
|
6 points or so. I think that diffusion has a little more physical |
| 25 |
|
justification. |
| 26 |
|
- clean up ggl90_calc in the hope of reducing memory usage (this hope |
| 27 |
|
was in vain) |
| 28 |
|
- mask tke-variable in ggl90_init |
| 29 |
|
o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass) |
| 30 |
|
o fix biharmonic diffusion on CS-grid. |
| 31 |
|
o more obcs stuff |
| 32 |
|
- added obcs_external_fields_load as an alternative to the EXF-pkg option |
| 33 |
|
for reading boundary values. This routine is called from |
| 34 |
|
obcs_prescribe_read |
| 35 |
|
- updated obcs_check |
| 36 |
|
- changed sponge layer relaxation parameter units for days to seconds |
| 37 |
|
- turned off sponge layer by default |
| 38 |
|
- changed argument list of OBCS_CALC to myTime+deltaTclock |
| 39 |
|
- fixed about 35 bugs in obcs_external_fields_load |
| 40 |
|
|
| 41 |
|
checkpoint55c_post |
| 42 |
|
o obcs stuff |
| 43 |
|
- new runtime flags useOBCSprescribe, useOBCSbalance |
| 44 |
|
- re-arranged obcs_calc |
| 45 |
|
- moved exf_getobcs to obcs_prescibe_read |
| 46 |
|
obcs_prescibe_read is called after ORLANSKI stuff |
| 47 |
|
and independent of it (executable can contain all). |
| 48 |
|
- updated obcs_check |
| 49 |
|
- added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE. |
| 50 |
|
These may be necessary only if tangential velocities are |
| 51 |
|
prescribed at OB, not sure, needs testing. |
| 52 |
|
o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments |
| 53 |
|
which simplifies the calls and passes the ifc check-bounds test |
| 54 |
|
|
| 55 |
|
checkpoint55b_post |
| 56 |
|
o add a 2D scalar, Z location, exchange_2 routine. |
| 57 |
|
o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows |
| 58 |
|
to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)] |
| 59 |
|
affects advect_cs results (for the wrong reason): update output.txt |
| 60 |
|
o use a more standard discretization for biharmonic viscosity ; |
| 61 |
|
(original version still available with #define MOM_VI_ORIGINAL_VISCA4 ) |
| 62 |
|
affects results of dome set-up: update output.txt |
| 63 |
|
o fix gad_advection.F (CubedSphere part), back to version 1.23 |
| 64 |
|
o fix bug in mom_vi_del2uv.F (CubedSphere part). |
| 65 |
|
|
| 66 |
|
checkpoint55a_post |
| 67 |
|
o merged code to |
| 68 |
|
* prescribe/read time-dependent open boundaries |
| 69 |
|
(works in conjunction with exf, cal) |
| 70 |
|
* sponge layer code for open boundaries |
| 71 |
|
* each boundary N/S/E/W now has its own CPP option |
| 72 |
|
(healthy for the adjoint) |
| 73 |
|
|
| 74 |
|
checkpoint55 |
| 75 |
|
o up-to-date adjoint of previous breaks |
| 76 |
|
- natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix |
| 77 |
|
- global_ocean_ebm: adjoint still needs fix (TLM ok) |
| 78 |
|
- global_ocean.90x40x15: extended GMREDI_OPTIONS.h |
| 79 |
|
- carbon: * remove tr1-related adjoint verification |
| 80 |
|
* add ptracer as control variable |
| 81 |
|
o remove all tr1-related code (ALLOW_PASSIVE_TRACER) |
| 82 |
|
(adjoint stuff still has some tr1 'names', but all use ptracer arrays) |
| 83 |
|
|
| 84 |
|
checkpoint54f_post |
| 85 |
|
o in verification/carbin/ remove experiment related to |
| 86 |
|
ALLOW_PASSIVE_TRACER (array tr1 etc) |
| 87 |
|
code_ad/ input_ad/ results_ad |
| 88 |
|
|
| 89 |
|
o add two new packages |
| 90 |
|
- ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993) |
| 91 |
|
+ subject to optimization (memory) |
| 92 |
|
- opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997) |
| 93 |
|
+ subject to reordering (many GOTOs in the original code) |
| 94 |
|
+ so far opps is called for every (i,j) point, and then operates in |
| 95 |
|
the vertical; one may want to reorder the scheme in order operate in |
| 96 |
|
horizontal slabs at the cost of (a lot of) memory, at least ten new 3D |
| 97 |
|
fields) |
| 98 |
|
o overhaul of IO so that we now have flags for MDSIO and/or MNC |
| 99 |
|
- all verification tests compile and run with linux_ia32_g77 |
| 100 |
|
- defaults are compatible with current input files--nothing |
| 101 |
|
should change if you were not previously using MNC |
| 102 |
|
- MNC output has been added in numerous places (eg. timeave) |
| 103 |
|
but there are still a few writes not yet do-able with MNC |
| 104 |
|
(this is in progress) |
| 105 |
|
- flags now allow for either/or/both use of MDSIO and MNC and |
| 106 |
|
documentation will soon follow |
| 107 |
|
- numerous small formatting cleanups for ProTeX |
| 108 |
|
o add version info (via BUILD_INFO.h) to MNC and stdout |
| 109 |
|
|
| 110 |
|
checkpoint54e_post |
| 111 |
|
o add two new packages |
| 112 |
|
- pp81 (Packanowski and Philander, 1981), Richardson number and |
| 113 |
|
stratification dependent mixing |
| 114 |
|
- my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme |
| 115 |
|
- these scheme operate in a similar manner as KPP (without ghat, of |
| 116 |
|
course), however there is only one diffusivity that is used for both |
| 117 |
|
temperature and salinity (and passive tracers)ç |
| 118 |
|
o add offline package |
| 119 |
|
o add "verification/dic_example" which contains a dic-gchem-ptracer setup |
| 120 |
|
provided by Stephanie Dutkiewicz |
| 121 |
|
o genmake2: add ability to search for C compilers and cleanup test output |
| 122 |
|
- fixes recent SX-6 problems and should help with others (eg. HP-UX) |
| 123 |
|
|
| 124 |
checkpoint54d_post |
checkpoint54d_post |
| 125 |
o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed |
o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed |
| 126 |
o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong, |
o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong, |
