openmc.Complement¶
-
class
openmc.
Complement
(node)[source]¶ 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)[source]¶ Create a copy of this region - each of the surfaces in the region’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 region Return type: openmc.Region
-
get_surfaces
(surfaces=None)[source]¶ Recursively find and return all the surfaces referenced by the node
Parameters: surfaces (collections.OrderedDict, optional) – Dictionary mapping surface IDs to openmc.Surface
instancesReturns: surfaces – Dictionary mapping surface IDs to openmc.Surface
instancesReturn type: collections.OrderedDict
-
remove_redundant_surfaces
(redundant_surfaces)[source]¶ Recursively remove all redundant surfaces referenced by this region
New in version 0.12.
Parameters: redundant_surfaces (dict) – Dictionary mapping redundant surface IDs to class:openmc.Surface instances that should replace them.
-
rotate
(rotation, pivot=(0.0, 0.0, 0.0), order='xyz', inplace=False, memo=None)[source]¶ Rotate surface by angles provided or by applying matrix directly.
New in version 0.12.
Parameters: - rotation (3-tuple of float, or 3x3 iterable) – A 3-tuple of angles \((\phi, \theta, \psi)\) in degrees where the first element is the rotation about the x-axis in the fixed laboratory frame, the second element is the rotation about the y-axis in the fixed laboratory frame, and the third element is the rotation about the z-axis in the fixed laboratory frame. The rotations are active rotations. Additionally a 3x3 rotation matrix can be specified directly either as a nested iterable or array.
- pivot (iterable of float, optional) – (x, y, z) coordinates for the point to rotate about. Defaults to (0., 0., 0.)
- order (str, optional) – A string of ‘x’, ‘y’, and ‘z’ in some order specifying which rotation to perform first, second, and third. Defaults to ‘xyz’ which means, the rotation by angle \(\phi\) about x will be applied first, followed by \(\theta\) about y and then \(\psi\) about z. This corresponds to an x-y-z extrinsic rotation as well as a z-y’-x’’ intrinsic rotation using Tait-Bryan angles \((\phi, \theta, \psi)\).
- inplace (boolean) – Whether or not to return a new instance of Surface or to modify the coefficients of this Surface in place. Defaults to False.
- memo (dict or None) – Dictionary used for memoization
Returns: Translated region
Return type:
