openmc.Union¶
-
class
openmc.
Union
(*nodes)[source]¶ Union of two or more regions.
Instances of Union are generally created via the __or__ operator applied to two instances of
openmc.Region
. This is illustrated in the following example:>>> s1 = openmc.ZPlane(z0=0.0) >>> s2 = openmc.Sphere(R=637.1e6) >>> type(-s2 | +s1) <class 'openmc.region.Union'>
Parameters: *nodes – Regions to take the union of
Variables: - nodes (tuple of openmc.Region) – Regions to take the union of
- bounding_box (2-tuple of numpy.array) – Lower-left and upper-right coordinates of an axis-aligned bounding box
-
clone
(memo=None)[source]¶ Create a copy of this region - each of the surfaces in the union’s nodes will be cloned and will have new unique IDs.
Parameters: memo (dict or None) – A nested dictionary of previously cloned objects. This parameter is used internally and should not be specified by the user. Returns: clone – The clone of this union Return type: openmc.Union
