10.2.2. armicontrib.dif3d.executers module

Contains components that prepare, execute, and read output from DIF3D.

Anything wanting DIF3D results should instantiate these objects and use them. The objects here are intended to be short lived e.g. created, used, and destroyed.

The Dif3dExecuter orchestrates the tasks of interpreting relevant case settings, writing a DIF3D input file, executing DIF3D upon that file, and reading the resultant DIF3D output files back in. The results read from the output files are then applied to the reactor model. In addition to dealing specifically with DIF3D itself, this sub-classes the GlobalFluxExecuter, which assists in performing geometry transformations, flux-based parameter computation, and other tasks.

armi.physics.neutronics.globalFlux.globalFluxInterface.GlobalFluxExecuter

ARMI-provided base class to GlobalFluxExecuter.

Dif3dOptions

Options that control the behavior of the Executer and its components.

Dif3dCoreEvaluation

One particular client of this code that runs DIF3D on a core.

class armicontrib.dif3d.executers.Dif3dExecuter(options: armi.physics.neutronics.globalFlux.globalFluxInterface.GlobalFluxOptions, reactor)

Bases: armi.physics.neutronics.globalFlux.globalFluxInterface.GlobalFluxExecuter

A short-lived object that coordinates the prep, execution, and processing of a flux solve.

This is an implementation of ARMI’s DefaultExecuter and thus follows that pattern closely.

Parameters

• options (executionOptions.Dif3dOptions) – run settings

• armiObj (composite.ArmiObject) – The object representing the scope of the DIF3D run (e.g. the Core or SFP, etc.)
