__getitem__()

Grid.__getitem__(key: int | slice | ellipsis | tuple[int | slice | ellipsis, ...] | ndarray[Any, dtype[_ScalarType_co]]) → DataArraySource

Return grid coordinates indexed by (l, m, n, RZ).

Returned grid coordinates are in \((R, Z)\) which can be specified by l: radial, m: poloidal, n: torodial index.

Examples

>>> grid = Grid("zone0")
>>> grid[0, 0, 0, :].data  # (l=0, m=0, n=0)
array([3.593351e+00, 0.000000e+00])  # (R, Z) coordinates

>>> grid[:, -10, 0, :].data  # (radial coords at m=-10, n=0)
array([[3.600000e+00, 0.000000e+00],
        [3.593494e+00, 3.076000e-03],
        [3.560321e+00, 1.875900e-02],
        ...,
        [3.267114e+00, 1.573770e-01]])
