openmc.Complement

class openmc.Complement(node)

Complement of a region.

The Complement of an existing openmc.Region can be created by using the ~ operator as the following example demonstrates:

>>> xl = openmc.XPlane(-10.0)
>>> xr = openmc.XPlane(10.0)
>>> yl = openmc.YPlane(-10.0)
>>> yr = openmc.YPlane(10.0)
>>> inside_box = +xl & -xr & +yl & -yr
>>> outside_box = ~inside_box
>>> type(outside_box)
<class 'openmc.region.Complement'>

Parameters:

node (openmc.Region) – Region to take the complement of

Variables:

• node (openmc.Region) – Regions to take the complement of
• bounding_box (tuple of numpy.array) – Lower-left and upper-right coordinates of an axis-aligned bounding box

clone(memo=None)

Create a copy of this region - each of the surfaces in the complement’s node 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 complement Return type:openmc.Complement

get_surfaces(surfaces=None)

Recursively find and return all the surfaces referenced by the node

Parameters:surfaces (collections.OrderedDict, optional) – Dictionary mapping surface IDs to openmc.Surface instances Returns:surfaces – Dictionary mapping surface IDs to openmc.Surface instances Return type:collections.OrderedDict

translate(vector, memo=None)

Translate region in given direction

Parameters:

• vector (iterable of float) – Direction in which region should be translated
• memo (dict or None) – Dictionary used for memoization. This parameter is used internally and should not be specified by the user.

Returns:

Translated region

Return type:

openmc.Complement
