class domain

[philippemiron]

The physical_space class should be designed to account for nonuniform grid. I plan to create a main class defining the needed function (create_grid() and find_element()) with subclasses for:

• uniform grid
• nonuniform in latitude
• nonuniform in longitude
• totally unstructured,

to account for the specific cases.

• hexagonal grid

  • find_element(): q = (sqrt(3)/3 * x - 1/3 * y) / s and r = (2/3 * y) / s are center for hexagon of size s.

• Voronoi triangular grid

  • find element(): find the closest seed to a point (x,y), then the triangle in that Voronoi cell
