polaris.mesh.IcosahedralMeshStep.get_cell_width

static IcosahedralMeshStep.get_cell_width(subdivisions)

Get the approximate cell width for an icosahedral mesh given either a number of subdivisions of the icosahedron. As a rule of thumb:

subdivisions	cell width (km)
5	240
6	120
7	60
8	30
9	15
10	7.5
11	3.8
12	1.9
13	0.94

Parameters:

subdivisions (int) – The number of subdivisions of the icosahedron to make

Returns:

cell_width (float) – The approximate size in km of each cell
