4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o reduce number of exch calls in shap_filt (s2).
8    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
9      truncation level) 4/5 MLAdjust test results (11&12 digits match).
10    
11    checkpoint57t_post
12    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
13    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
14      same truncation, independent of the face number: affects affects several
15      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
16    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
17      note that biharmonic viscosity + no-slip was not tested in any experiment.
18    o fix bug in non-linear free-surf side-drag ; generate new output for
19      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
20    o make mnc honor the writeBinaryPrec flag for most kinds of output
21    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
22    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
23      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
24    o add brackets in multi-terms sum to get same truncation, independent of
25      the face number (manage to get exactly same value of gU,gV at the cs-edge)
26      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
27    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
28      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
29      a maximum grid-scale Reynolds number.  Also, changes all length calculations
30      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
31      Suggested values of viscosity parameters found in mom_calc_visc.
32      Many new viscosity diagnostics available.
33    
34    checkpoint57s_post
35    o Add clearing-house for viscosity calculations, mom_calc_visc and
36      correct numerous bugs in LeithD and Smagorinsky discretizations.  
37      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
38      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
39      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
40      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
41      The Strain-Tension form is now called with useStrainTensonVisc=.true.
42      ViscAhStrain and viscAhTension are now retired.
43    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
44    o In response to JMC's bug report, genmake2 now ignores any soft-links
45      that it finds in the *current* directory when searching for files.
46      Soft-links found in any other source directories will still work as
47      they did before.
48    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
49      a C routine to unlimit the stack size
50    o mnc-ify pkg/aim snapshot vars
51    o mnc-ify pkg/land as requested by Daniel
52    o various changes to mnc including:
53      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
54      - output can now be grouped so that all files within a group
55          change the ITER portion of their names in lock-step together
56      - can now read ("global") PER-FACE (in addition to PER-TILE) files
57          and works with both EXCH1 and EXCH2 (but needs more testing)
58      - writing works for all verification test cases w/ g77 on Linux
59    
60    checkpoint57r_post
61    o make MNC variable initialization happen earlier
62    o add diagnostics for (almost) each term of the momentum Eq.
63  o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.  o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
64  o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)  o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
65  o remove MINIMAL_TAVE_OUTPUT option ;  o remove MINIMAL_TAVE_OUTPUT option ;
