A cylindrical polar grid.
The grid can be initialized by passing the w, z, and phi coordinates of cell walls:
>>> grid = CylindricalPolarGrid(w_wall, z_wall, p_wall)
where w_wall, z_wall, and p_wall are 1-d sequences of wall positions. The number of cells in the resulting grid will be one less in each dimension that the length of these arrays.
CylindricalPolarGrid objects may contain multiple quantities (e.g. density, specific energy). To access these, you can specify the name of the quantity as an item:
>>> grid['density']
which is no longer a CylindricalPolarGrid object, but a CylindricalPolarGridView object. When setting this for the first time, this can be set either to another CylindricalPolarGridView object, an external h5py link, or an empty list. For example, the following should work:
>>> grid['density_new'] = grid['density']
CylindricalPolarGridView objects allow the specific dust population to be selected as an index:
>>> grid['density'][0]
Which is also a CylindricalPolarGridView object. The data can then be accessed with the array attribute:
>>> grid['density'][0].array
which is a 3-d array of the requested quantity.
