Revision 1.1 - (show annotations) (download)
Wed Feb 12 00:41:59 2014 UTC (8 years, 11 months ago) by jmc
Branch: MAIN
- add a short README file ;
- reduce differences in main parameter file "data" across the 5 test exp.

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 input files are real*8 (see matlab script input/genit.m )
9
10 start from initial density field (given by initial Temp), no forcing

27 Notes:
28 1) Stain-Tension viscosity formulation is used when setting
29 useStrainTensionVisc=.TRUE.,
30 default is .False., to use vorticity & divergence formulation
31 2) test 1.leith (input.1.leith) starts from a pickup-file,
32 all other test exp. start from iter0=0
33 3) test with Biharmonic visc. are using:
34 viscC4leith = viscC4leithD = 1.85,
35 viscC4smag = 1.,
36 viscA4GridMax = 1.,
37 4) test with Harmonic visc. are using:
38 viscC2leith = viscC2leithD=1.85,
39 viscC2smag = 1.,
40 viscAhGridMax = 1.,
