====================
What's New in 0.13.0
====================
.. currentmodule:: openmc
-------
Summary
-------
This release of OpenMC includes several noteworthy and unique features. Most
importantly, mesh-based weight windows have been added and work with all
supported mesh types (regular, rectilinear, cylindrical, spherical, and
unstructured). Other additions include torus surfaces, an ability to place
CAD-based geometries in universes, a feature to export/import physical
properties, and a filter for particle time.
There is one breaking changing in the Python API. The
:class:`openmc.deplete.Operator` class used to accept :class:`~openmc.Geometry`
and :class:`~openmc.Settings` objects as its first two arguments; users now need
to pass a :class:`~openmc.model.Model` class instead.
The minimum supported Python version is now 3.6.
------------
New Features
------------
- Variance reduction using mesh-based weight windows is now possible with the
:class:`~openmc.WeightWindows` class.
- Users can now model axis-aligned tori using the :class:`~openmc.XTorus`,
:class:`~openmc.YTorus`, and :class:`~openmc.ZTorus` classes.
- DAGMC CAD-based geometries can now be placed in a universe using
:class:`~openmc.DAGMCUniverse`, allowing users to combine CSG and CAD-based
geometry in a single model.
- The C/C++ API has two new functions ``openmc_properties_export`` and
``openmc_properties_import`` with corresponding Python API bindings,
:func:`~openmc.lib.export_properties` and
:func:`~openmc.lib.import_properties`. These functions allow physical
properties (temperatures, densities, material compositions) to be written to
an HDF5 file and re-used for subsequent simulations.
- A new :class:`~openmc.stats.PowerLaw` univariate distribution
- The capabilities of the :class:`~openmc.Model` class have been substantially
expanded (e.g., the :meth:`~openmc.model.Model.deplete`,
:meth:`~openmc.model.Model.plot_geometry`, and
:meth:`~openmc.model.Model.rotate_cells` methods).
- A new :class:`~openmc.TimeFilter` class that allows tallies to be filtered
by the particle's time, which is now tracked.
- The :class:`~openmc.Source` class now allows you to specify a time
distribution.
- The new :class:`~openmc.CylindricalMesh` and :class:`~openmc.SphericalMesh`
can be used for mesh tallies over cylidrical and spherical meshes,
respectively.
- Geometry plotting, which used to produce the files in the unusual .ppm format,
now produces .png files by default.
---------
