armi.nuclearDataIO.cccc.rzflux module¶

Module for reading/writing RZFLUX CCCC interface files.

RZFLUX contains Regular Zone Flux, or multigroup flux by neutron energy group in each zone. It also can hold some convergence and neutron balance information.

The format is defined in [CCCC-IV].

Examples

>>> flux = rzflux.readBinary("RZFLUX")
>>> flux.groupFluxes[2, 0] *= 1.1
>>> rzflux.writeBinary(flux, "RZFLUX2")
>>> rzflux.writeAscii(flux, "RZFLUX2.ascii")

class armi.nuclearDataIO.cccc.rzflux.Convergence(value)[source]¶

Bases: enum.Enum

Convergence behavior flags for ITPS from RZFLUX file.

NO_ITERATIONS = 0¶

CONVERGED = 1¶

CONVERGING = 2¶

DIVERGING = 3¶

class armi.nuclearDataIO.cccc.rzflux.RzfluxData[source]¶

Bases: armi.nuclearDataIO.cccc.cccc.DataContainer

Data representation that can be read from or written to a RZFLUX file.

Notes

Analogous to a IsotxsLibrary for ISTOXS files.

class armi.nuclearDataIO.cccc.rzflux.RzfluxStream(data: armi.nuclearDataIO.cccc.cccc.DataContainer, fileName: str, fileMode: str)[source]¶

Bases: armi.nuclearDataIO.cccc.cccc.StreamWithDataContainer

Stream for reading to/writing from with RZFLUX data.

Parameters

flux (RzfluxData) – Data structure
fileName (str) – path to RZFLUX file
fileMode (str) – string indicating if fileName is being read or written, and in ascii or binary format

readWrite()[source]¶: Step through the structure of the file and read/write it.
