make_ace
(filename, temperatures=None, acer=True, xsdir=None, output_dir=None, pendf=False, error=0.001, broadr=True, heatr=True, gaspr=True, purr=True, evaluation=None, **kwargs)[source]¶ Generate incident neutron ACE file from an ENDF file
File names can be passed to
[acer, xsdir, pendf, broadr, heatr, gaspr, purr]
to specify the exact output for the given module. Otherwise, the files will be writen to the current directory or directory specified byoutput_dir
. Default file names mirror the variable names, e.g.heatr
output will be written to a file namedheatr
unless otherwise specified.Parameters: - filename (str) – Path to ENDF file
- temperatures (iterable of float, optional) – Temperatures in Kelvin to produce ACE files at. If omitted, data is produced at room temperature (293.6 K).
- acer (bool or str, optional) – Flag indicating if acer should be run. If a string is give, write the
resulting
ace
file to this location. Path of ACE file to write. Defaults to"ace"
- xsdir (str, optional) – Path of xsdir file to write. Defaults to
"xsdir"
in the same directory asacer
- output_dir (str, optional) – Directory to write output for requested modules. If not provided
and at least one of
[pendf, broadr, heatr, gaspr, purr, acer]
isTrue
, then write output files to current directory. If given, must be a path to a directory. - pendf (str, optional) – Path of pendf file to write. If omitted, the pendf file is not saved.
- error (float, optional) – Fractional error tolerance for NJOY processing
- broadr (bool or str, optional) – Indicating whether to Doppler broaden XS when running NJOY. If string, write the output tape to this file.
- heatr (bool or str, optional) – Indicating whether to add heating kerma when running NJOY. If string, write the output tape to this file.
- gaspr (bool or str, optional) – Indicating whether to add gas production data when running NJOY. If string, write the output tape to this file.
- purr (bool or str, optional) – Indicating whether to add probability table when running NJOY. If string, write the output tape to this file.
- evaluation (openmc.data.endf.Evaluation, optional) – If the ENDF file contains multiple material evaluations, this argument indicates which evaluation should be used.
- **kwargs – Keyword arguments passed to
openmc.data.njoy.run()
Raises: subprocess.CalledProcessError
– If the NJOY process returns with a non-zero statusIOError
– Ifoutput_dir
does not point to a directory
