Introducing LAKE_JERSEY test for Nesting.

[arango]

A new idealized test case is introduced for nesting applications, LAKE_JERSEY. It can be found in the test repository. It can configured with one or two refinement grids (1:3 ratio): bottom-left refinement grid and top-right refinement grid. The user can have three different nesting application using one of the following input scripts:

• ocean_lake_jersey_nested2_bot.in for coarse and bottom-left refinement grid. The following figures show free-surface, surface temperature and salinity after 2 days of simulation:

• ocean_lake_jersey_nested2_top.in for coarse and top-right refinement grid. The following figures show free-surface, surface temperature and salinity after 2 days of simulation:

• ocean_lake_jersey_nested3.in for coarse and both bottom-left and top-right refinement grids.

The plots above were made with the Matlab script plot_nesting.m from the repository. For example, for the 3-grid applications we need to compute first the grid structure:

  Hnames = {'lake_jersey_his_coarse.nc',       ...
            'lake_jersey_his_refined_bot.nc',  ...
            'lake_jersey_rst_refined_top.nc'};
  G = grids_structure(Hnames);
  F = plot_nesting(G, Hnames, 'salt', 97, 8);

Many thanks to John Wilkin for his help configuring this test case.
