5      ==============================      ==============================
6    
7    o pkg/seaice + obcs:
8     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
9       equivalent of assuming no tracer gradient outside the OB region.
10       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
11     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
12       after changes above);
13     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
14       only at OB location (instead of over a band of OLx width).
15    o pkg/seaice:
16     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
17       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
18    o pkg/obcs:
19      - split header file "OBCS.h" into 4 separated files:
20        OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
21       Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
22         (contain no conditional statement which depends on OBCS options).
23      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
24        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
25    o ctrl, cost, grdchk & autodiff pkgs:
26      - make options file more standard (like other {PKG}_OPTIONS.h file but
27        with AD_CONFIG.h); clean-up some of the included header files.
28    o pkg/obcs:
29      - do not mask tracer when applying OB (tracer == 0 could generate problems)
30      - apply tracer OB values to tracer field only at OB location (instead of
31        over a band of OLx width)
32      - clean-up obcs_apply_w.F & obcs_apply_eta.F (since less calls to these S/R)
33      - remove OBCS_MULTIDIM_OLD_VERSION code in gad_advection.F and remove
34        obcs_apply_tloc.F & obcs_apply_sloc.F
35    o obcs in model/src:
36      - call OBCS_APPLY_W only if NonHydrostatic.
37      - call OBCS_APPLY_ETA only if NonLinFreeSurf.
38      - reset dEtaHdt and wVel to zero outside OB interior region ;
39      - leave tracer unchanged outside OB interior region: This has no effect
40        on the solution but just to prevent unrealistic tracer value outside OB.
41      - zero out velocity outside OB interior region: This has no effect on
42        the solution but just to prevent unrealistic velocity outside OB.
43    o obcs and non-lin free-surf:
44       move call to OBCS_APPLY_R_STAR from update_r_star.F to calc_r_star.F
45       and call to OBCS_APPLY_SURF_DR from update_surf_dr.F to calc_surf_dr.F
46       + add argument "etaFld" to OBCS_APPLY_R_STAR & OBCS_APPLY_SURF_DR:
47       this fixes missing EXCH + get consistent eta OB value (+ fix restart).
48       update results of test-exp. exp4(nlfs).
49    o exp4 (nlfs) test-exp:
50       use OBC for Eta at Western & Eastern OB (to test prescribing Eta
51       with NonLin-FreeSurf); update output.nlfs.txt
52    o obcs and 2d/3d solver norm:
53       use interior masks (maskInC) to cancel out cg2d & cg3d matrix coeff at OB
54       and outside OB interior region (will allow to place OB further inside the
55       domain). Depending on the domain, can affects cg2d-Norm (previous
56       cancellation outside OB was only partial), e.g. in exp4 & obcs_ctrl,
57       and cg3d-Norm (previous Norm was computed before canceling OB terms),
58       e.g. in tutorial_plume_on_slope.
59      - update output of exp.: exp4 (x2), obcs_ctrl and tutorial_plume_on_slope.
60  o pkg rbcs:  o pkg rbcs:
61    - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h    - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h
62    - add capability to apply relaxation to horizontal velocity uVel & vVel.    - add capability to apply relaxation to horizontal velocity uVel & vVel.
