make_ace_thermal
(filename, filename_thermal, temperatures=None, ace='ace', xsdir=None, output_dir=None, error=0.001, iwt=2, evaluation=None, evaluation_thermal=None, **kwargs)[source]¶ Generate thermal scattering ACE file from ENDF files
Parameters: - filename (str) – Path to ENDF neutron sublibrary file
- filename_thermal (str) – Path to ENDF thermal scattering sublibrary file
- temperatures (iterable of float, optional) – Temperatures in Kelvin to produce data at. If omitted, data is produced at all temperatures given in the ENDF thermal scattering sublibrary.
- ace (str, optional) – Path of ACE file to write
- xsdir (str, optional) – Path of xsdir file to write. Defaults to
"xsdir"
in the same directory asace
- output_dir (str, optional) – Directory to write ace and xsdir files. If not provided, then write output files to current directory. If given, must be a path to a directory.
- error (float, optional) – Fractional error tolerance for NJOY processing
- iwt (int) – iwt parameter used in NJOR/ACER card 9
- evaluation (openmc.data.endf.Evaluation, optional) – If the ENDF neutron sublibrary file contains multiple material evaluations, this argument indicates which evaluation to use.
- evaluation_thermal (openmc.data.endf.Evaluation, optional) – If the ENDF thermal scattering sublibrary file contains multiple material evaluations, this argument indicates which evaluation to use.
- **kwargs – Keyword arguments passed to
openmc.data.njoy.run()
Raises: subprocess.CalledProcessError
– If the NJOY process returns with a non-zero status
