openmc.stats.Box

class openmc.stats.Box(lower_left: Sequence[float], upper_right: Sequence[float], only_fissionable: bool = False)[source]

Uniform distribution of coordinates in a rectangular cuboid.

Parameters:

  • lower_left (Iterable of float) – Lower-left coordinates of cuboid

  • upper_right (Iterable of float) – Upper-right coordinates of cuboid

  • only_fissionable (bool, optional) –

    Whether spatial sites should only be accepted if they occur in fissionable materials

    Deprecated since version 0.15.0: Use the constraints argument when defining a source object instead.

Variables:

  • lower_left (Iterable of float) – Lower-left coordinates of cuboid

  • upper_right (Iterable of float) – Upper-right coordinates of cuboid

  • only_fissionable (bool, optional) –

    Whether spatial sites should only be accepted if they occur in fissionable materials

    Deprecated since version 0.15.0: Use the constraints argument when defining a source object instead.
