Grid

The two-dimensional grid of equilateral triangles is created with the m-file twodgrid.m, which can be downloaded from

http://suntans.stanford.edu/downloads_stanford .

As shown in Figure 11, it is 3 km long by 1 km wide with a total of 1215 equilateral triangles with edge lengths of 75 m. The eastern and southern boundaries are marked as type 2 edges. These will be specified in boundaries.c. The depth is 10 m and is specified in initialization.c as

return 10;

There are 10 vertical levels (suntans.dat: Nkmax = 10).
