@ -45,6 +45,23 @@ with the :envvar:`OPENMC_CROSS_SECTIONS` environment variable. It is recommended
to add a line in your ``.profile`` or ``.bash_profile`` setting the
:envvar:`OPENMC_CROSS_SECTIONS` environment variable.
RuntimeError: Failed to open HDF5 file with mode 'w': summary.h5
****************************************************************
This often occurs when working with the Python API and executing multiple OpenMC
runs in a script. If an :class:`openmc.StatePoint` is open in the Python interpreter,
the file handle of the statepoint file as well as the linked `summary.h5` file will
be unavailable for writing, causing this error to appear. To avoid this situation,
it is recommended that data be extracted from statepoint files in a context manager:
.. code-block:: python
with openmc.StatePoint('statepoint.10.h5') as sp:
k_eff = sp.k_combined
or that the :meth:`StatePoint.close` method is called before executing a subsequent
OpenMC run.
