openmc.DAGMCUniverse¶

class openmc.DAGMCUniverse(filename, universe_id=None, name='', auto_geom_ids=False, auto_mat_ids=False)[source]¶

A reference to a DAGMC file to be used in the model.

New in version 0.13.0.

Parameters

filename (str) – Path to the DAGMC file used to represent this universe.
universe_id (int, optional) – Unique identifier of the universe. If not specified, an identifier will automatically be assigned.
name (str, optional) – Name of the universe. If not specified, the name is the empty string.
auto_geom_ids (bool) – Set IDs automatically on initialization (True) or report overlaps in ID space between CSG and DAGMC (False)
auto_mat_ids (bool) – Set IDs automatically on initialization (True) or report overlaps in ID space between OpenMC and UWUW materials (False)

Variables

id (int) – Unique identifier of the universe
name (str) – Name of the universe
filename (str) – Path to the DAGMC file used to represent this universe.
auto_geom_ids (bool) – Set IDs automatically on initialization (True) or report overlaps in ID space between CSG and DAGMC (False)
auto_mat_ids (bool) – Set IDs automatically on initialization (True) or report overlaps in ID space between OpenMC and UWUW materials (False)

create_xml_subelement(xml_element, memo=None)[source]¶

Add the universe xml representation to an incoming xml element

Parameters

xml_element (xml.etree.ElementTree.Element) – XML element to be added to
memo (set or None) – A set of object id’s representing geometry entities already written to the xml_element. This parameter is used internally and should not be specified by users.

Returns

Return type

None
