Variables:

• energy_groups (openmc.mgxs.EnergyGroups) – Energy group structure.
• inverse_velocities (Iterable of Real) – Inverse of velocities, units of sec/cm
• xsdatas (Iterable of openmc.XSdata) – Iterable of multi-Group cross section data objects

add_xsdata(xsdata)

Parameters:xsdata (openmc.XSdata) – MGXS information to add

add_xsdatas(xsdatas)

Add multiple xsdatas to the file.

Parameters:xsdatas (tuple or list of openmc.XSdata) – XSdatas to add

export_to_xml(filename='mgxs.xml')

Create an mgxs.xml file that can be used for a simulation.

Parameters:filename (str, optional) – filename of file, default is mgxs.xml

remove_xsdata(xsdata)
