openmc.IndependentSource¶
- class openmc.IndependentSource(space: Optional[Spatial] = None, angle: Optional[UnitSphere] = None, energy: Optional[Univariate] = None, time: Optional[Univariate] = None, strength: float = 1.0, particle: str = 'neutron', domains: Optional[Sequence[Union[Cell, Material, Universe]]] = None)[source]¶
Distribution of phase space coordinates for source sites.
New in version 0.14.0.
- Parameters
space (openmc.stats.Spatial) – Spatial distribution of source sites
angle (openmc.stats.UnitSphere) – Angular distribution of source sites
energy (openmc.stats.Univariate) – Energy distribution of source sites
time (openmc.stats.Univariate) – time distribution of source sites
strength (float) – Strength of the source
particle ({'neutron', 'photon'}) – Source particle type
domains (iterable of openmc.Cell, openmc.Material, or openmc.Universe) – Domains to reject based on, i.e., if a sampled spatial location is not within one of these domains, it will be rejected.
- Variables
space (openmc.stats.Spatial or None) – Spatial distribution of source sites
angle (openmc.stats.UnitSphere or None) – Angular distribution of source sites
energy (openmc.stats.Univariate or None) – Energy distribution of source sites
time (openmc.stats.Univariate or None) – time distribution of source sites
strength (float) – Strength of the source
type (str) – Indicator of source type: ‘independent’
versionadded: (..) – 0.14.0:
particle ({'neutron', 'photon'}) – Source particle type
ids (Iterable of int) – IDs of domains to use for rejection
domain_type ({'cell', 'material', 'universe'}) – Type of domain to use for rejection

- Parameters
elem (lxml.etree._Element) – XML element
meshes (dict) – Dictionary with mesh IDs as keys and openmc.MeshBase instaces as values
- Returns
Source generated from XML element
- Return type
