pyopensn.post.VolumePostprocessor

class pyopensn.post.VolumePostprocessor

Volume post-processor.

Wrapper of opensn::VolumePostprocessor.

Execute(self: pyopensn.post.VolumePostprocessor) → None

Execute the postprocessor

GetValue(self: pyopensn.post.VolumePostprocessor) → numpy.ndarray[numpy.float64]

Returns the value of the postprocessor.

Rows correspond to the spatial restriction (i.e. logical volumes, if specified) Columns correspond to the energy restrictions (i.e. groups, or groups within a groupset if specified)

__init__(self: pyopensn.post.VolumePostprocessor, **kwargs) → None

Construct a volume post processor object.

Parameters:

  • problem (LBSProblem) – A handle to an existing LBS problem.

  • block_ids (List[int], optional) – Block restriction for the postprocessor. Empty/unspecified means no block restriction.

  • logical_volumes (List[LogicalVolume], optional) – Logical volumes to restrict the computation to.

  • value_type (str, optional) – Type of value to compute: ‘integral’ (default), ‘max’, ‘min’, or ‘avg’.

  • group (int, optional) – Single group to compute (mutually exclusive with groupset).

  • groupset (int, optional) – Single groupset to compute (mutually exclusive with group).

  • multiplier (float, optional) – Constant multiplier. Default 1.0.

  • group_multipliers (List[float], optional) – Group-wise multipliers, one per group.

  • xs_multiplier (str, optional) – Name of a cross-section multiplier.
