openmc.model.Model

class openmc.model.Model(geometry=None, materials=None, settings=None, tallies=None, cmfd=None, plots=None)

Model container.

This class can be used to store instances of openmc.Geometry, openmc.Materials, openmc.Settings, openmc.Tallies, openmc.Plots, and openmc.CMFD, thus making a complete model. The Model.export_to_xml() method will export XML files for all attributes that have been set. If the Model.materials() attribute is not set, it will attempt to create a materials.xml file based on all materials appearing in the geometry.

Parameters:

• geometry (openmc.Geometry, optional) – Geometry information
• materials (openmc.Materials, optional) – Materials information
• settings (openmc.Settings, optional) – Settings information
• tallies (openmc.Tallies, optional) – Tallies information
• cmfd (openmc.CMFD, optional) – CMFD information
• plots (openmc.Plots, optional) – Plot information

Variables:

• geometry (openmc.Geometry) – Geometry information
• materials (openmc.Materials) – Materials information
• settings (openmc.Settings) – Settings information
• tallies (openmc.Tallies) – Tallies information
• cmfd (openmc.CMFD) – CMFD information
• plots (openmc.Plots) – Plot information

export_to_xml()

Export model to XML files.

run(**kwargs)

Creates the XML files, runs OpenMC, and returns k-effective

Parameters:**kwargs – All keyword arguments are passed to openmc.run Returns:Combined estimator of k-effective from the statepoint Return type:2-tuple of float
