updated

1 jmc 1.1 Simple set-up to test flow-dependent horizontal viscosity implementation.
2    
3     Domain size is 50 x 26 x 40 grid-cells,
4     with uniform resolution dx=dy= 1.km , dz = 5.m
5    
6     Zonally re-entrant, flat bottom channel (closed by Northern Wall @ j=26)
7    
8 jmc 1.2 input files are real*8 (see matlab script input/gendata.m )
9 jmc 1.1
10     start from initial density field (given by initial Temp), no forcing
11    
12 jmc 1.2 Test Exp. | Momentum | Viscosity | useFullLeith | Biharmonic | side-drag |
13     | formulation | formulation | | vs harmonic| (no_slip BC)|

15     standard | Vector-Inv. | Vort-Div | FullLeith | viscC4 | No |

17     ----------------------------------------------------------------------------------
18     .A4FlxF | Flux-Form | FLux-Form | FullLeith | viscC4 | Yes |
19     ----------------------------------------------------------------------------------
20     .AhFlxF | Flux-Form | Flux-Form | No | viscC2 | No |
21     ----------------------------------------------------------------------------------
22     .AhVrDv | Vector-Inv. | Vort-Div | FullLeith | viscC2 | Yes |
23     ----------------------------------------------------------------------------------
24     .AhStTn | Vector-Inv. | Strain-Tens | FullLeith | viscC2 | Yes |
25     ----------------------------------------------------------------------------------
26 jmc 1.1
27     Notes:
28     1) Stain-Tension viscosity formulation is used when setting
29     useStrainTensionVisc=.TRUE.,
30 jmc 1.2 and currently only available with Vector-Invariant momentum.
31     Default is .False., to use Vorticity & Divergence formulation
32     (pkg/mom_vecinv) or Flux-Form formulation (pkg/mom_fluxform)
33     2) test .A4FlxF (input.A4FlxF) starts from a pickup-file,
34 jmc 1.1 all other test exp. start from iter0=0
35     3) test with Biharmonic visc. are using:
36     viscC4leith = viscC4leithD = 1.85,
37     viscC4smag = 1.,
38     viscA4GridMax = 1.,
39     4) test with Harmonic visc. are using:
40     viscC2leith = viscC2leithD=1.85,
41     viscC2smag = 1.,
42     viscAhGridMax = 1.,
