# openmc.stats.PolarAzimuthal¶

class openmc.stats.PolarAzimuthal(mu=None, phi=None, reference_uvw=(0.0, 0.0, 1.0))[source]

Angular distribution represented by polar and azimuthal angles

This distribution allows one to specify the distribution of the cosine of the polar angle and the azimuthal angle independently of one another. The polar angle is measured relative to the reference angle.

Parameters
• mu (openmc.stats.Univariate) – Distribution of the cosine of the polar angle

• phi (openmc.stats.Univariate) – Distribution of the azimuthal angle in radians

• reference_uvw (Iterable of float) – Direction from which polar angle is measured. Defaults to the positive z-direction.

Variables
classmethod from_xml_element(elem)[source]

Generate angular distribution from an XML element

Parameters

elem (xml.etree.ElementTree.Element) – XML element

Returns

Angular distribution generated from XML element

Return type

openmc.stats.PolarAzimuthal

to_xml_element()[source]

Return XML representation of the angular distribution

Returns

element – XML element containing angular distribution data

Return type

xml.etree.ElementTree.Element
