openmc.TimeFilter

class openmc.TimeFilter(values, filter_id=None)

Bins tally events based on the particle’s time.

New in version 0.13.0.

Parameters

• values (iterable of float) – A list of values for which each successive pair constitutes a range of time in [s] for a single bin

• filter_id (int) – Unique identifier for the filter

Variables

• values (numpy.ndarray) – An array of values for which each successive pair constitutes a range of time in [s] for a single bin

• id (int) – Unique identifier for the filter

• bins (numpy.ndarray) – An array of shape (N, 2) where each row is a pair of time in [s] for a single filter bin

• num_bins (int) – The number of filter bins

check_bins(bins)

Make sure given bins are valid for this filter.

Raises

• TypeError –

• ValueError –

get_bin_index(filter_bin)

Returns the index in the Filter for some bin.

Parameters

filter_bin (int or tuple) – The bin is the integer ID for ‘material’, ‘surface’, ‘cell’, ‘cellborn’, and ‘universe’ Filters. The bin is an integer for the cell instance ID for ‘distribcell’ Filters. The bin is a 2-tuple of floats for ‘energy’ and ‘energyout’ filters corresponding to the energy boundaries of the bin of interest. The bin is an (x,y,z) 3-tuple for ‘mesh’ filters corresponding to the mesh cell of interest.

Returns

filter_index – The index in the Tally data array for this filter bin.

Return type

int
