openmc.stats.SphericalIndependent¶
- class openmc.stats.SphericalIndependent(r, theta, phi, origin=(0.0, 0.0, 0.0))[source]¶
Spatial distribution represented in spherical coordinates.
This distribution allows one to specify coordinates whose \(r\), \(\theta\), and \(\phi\) components are sampled independently from one another and centered on the coordinates (x0, y0, z0).
- Parameters
r (openmc.stats.Univariate) – Distribution of r-coordinates in a reference frame specified by the origin parameter
theta (openmc.stats.Univariate) – Distribution of theta-coordinates (angle relative to the z-axis) in a reference frame specified by the origin parameter
phi (openmc.stats.Univariate) – Distribution of phi-coordinates (azimuthal angle) in a reference frame specified by the origin parameter
origin (Iterable of float, optional) – coordinates (x0, y0, z0) of the center of the spherical reference frame for the source. Defaults to (0.0, 0.0, 0.0)
- Variables
r (openmc.stats.Univariate) – Distribution of r-coordinates in the local reference frame
theta (openmc.stats.Univariate) – Distribution of theta-coordinates (angle relative to the z-axis) in the local reference frame
phi (openmc.stats.Univariate) – Distribution of phi-coordinates (azimuthal angle) in the local reference frame
origin (Iterable of float, optional) – coordinates (x0, y0, z0) of the center of the spherical reference frame. Defaults to (0.0, 0.0, 0.0)
