Constructor & Destructor Documentation

◆ MeshTally()

MeshTally::MeshTally ( const InputParameters & parameters )

Member Function Documentation

◆ addScore()

void TallyBase::addScore ( const std::string & score )

inherited

Add a score to this tally.

Parameters

[in] score score to add

◆ applyTriggersToLocalTally()

void TallyBase::applyTriggersToLocalTally ( openmc::Tally * tally )

protectedinherited

Applies triggers to a tally. This is often the local tally wrapped by this object.

Parameters

[in] tally the tally to apply triggers to

◆ checkMeshTemplateAndTranslations()

void MeshTally::checkMeshTemplateAndTranslations ( ) const

protected

Check the setup of the mesh template and translations. Because a simple copy transfer is used to write a mesh tally onto the [Mesh], we require that the meshes are identical - both in terms of the element ordering and the actual dimensions of each element. This function performs as many checks as possible to ensure that the meshes are indeed identical.

◆ computeSumAndMean()

void TallyBase::computeSumAndMean ( )

inherited

A function which computes and stores the sum and mean of the tally across all bins for a particular score.

◆ fillElementalAuxVariable()

void TallyBase::fillElementalAuxVariable	(	const unsigned int &	var_num,
		const std::vector< unsigned int > &	elem_ids,
		const Real &	value
	)

protectedinherited

Set an auxiliary elemental variable to a specified value

Parameters

[in]	var_num	variable number
[in]	elem_ids	element IDs to set
[in]	value	value to set

◆ getAuxVarNames()

const std::vector<std::string>& TallyBase::getAuxVarNames ( ) const

inlineinherited

Gets the auxvariable names for use in creating and storing tally results. This allows for the splitting of tally results into energy bins, angular bins, etc.

Returns: vector of variable names to be associated with this tally

◆ getMean()

const Real& TallyBase::getMean ( unsigned int local_score ) const

inlineinherited

Get the mean for a score summed over all bins.

Parameters

[in] local_score the index representing a tally score

Returns: mean for a score summed over all bins.

◆ getOutputs()

const std::vector<std::string>& TallyBase::getOutputs ( ) const

inlineinherited

Gets the output names to append to the end of the '_tally_name' when adding tally auxvariables for additional outputs.

Returns: additional tally outputs

◆ getScores()

const std::vector<std::string>& TallyBase::getScores ( ) const

inlineinherited

Get the list of scores this tally uses.

Returns: list of scores this tally uses

◆ getSum()

const Real& TallyBase::getSum ( unsigned int local_score ) const

inlineinherited

Get the sum for a score summed over all bins.

Parameters

[in] local_score the index representing a tally score

openmc::TallyEstimator TallyBase::getTallyEstimator ( ) const

inlineinherited

inherited

Get the OpenMC tally that this object wraps.

Returns: the OpenMC tally object

◆ hasOutputs()

bool TallyBase::hasOutputs ( ) const

inlineinherited

Check to see if this tally adds additional output variables or not.

Returns: whether this tally adds additional output variables or not

◆ hasTrigger()

bool TallyBase::hasTrigger ( ) const

inlineinherited

Check to see if this tally uses a trigger or not.

Returns: whether this tally uses a trigger or not

◆ initializeTally()

virtual void TallyBase::initializeTally ( )

virtualinherited

A function to initialize the tally object. Override with care.

◆ relaxAndNormalizeTally()

void TallyBase::relaxAndNormalizeTally	(	unsigned int	local_score,
		const Real &	alpha,
		const Real &	norm
	)

inherited

Relax the tally and normalize it according to some normalization factor 'norm'. This tends to either be the sum of the over all bins OR a global tally over the entire problem.

NOTE: This function relaxes the tally distribution, and not the actual magnitude of the sum. That is, we relax the shape distribution and then multiply it by the power (for k-eigenvalue) or source strength (for fixed source) of the current step before applying it to MOOSE. If the magnitude of the power or source strength is constant in time, there is zero error in this. But if the magnitude of the tally varies in time, we are basically relaxing the distribution of the tally, but then multiplying it by the current mean tally magnitude.

There will be very small errors in these approximations unless the power/source strength change dramatically with iteration. But because relaxation is itself a numerical approximation, this is still inconsequential at the end of the day as long as your problem has converged the relaxed tally to the raw (unrelaxed) tally.

Parameters

[in]	local_score	the local index of the current score to normalize
[in]	alpha	the relaxation factor
[in]	norm	the normalization factor

◆ renamesTallyVars()

bool TallyBase::renamesTallyVars ( ) const

inlineinherited

Check to see if the user has requested special names for the tallies.

Returns: whether this tally names stored values something other than '_tally_score'

◆ resetTally()

Reimplemented from TallyBase.

◆ spatialFilter()

virtual std::pair<unsigned int, openmc::Filter *> MeshTally::spatialFilter ( )

overridevirtual

Returns: a pair where the first entry is the filter index in the global filter array and the second entry is an OpenMC unstructured mesh filter

Implements TallyBase.

[in]	local_score	index into the tally's local array of scores which represents the current score being stored
[in]	global_score	index into the global array of tally results which represents the current score being stored

OpenMC unstructured mesh instance for use with mesh tallies.

◆ _mesh_template_filename

const std::string* MeshTally::_mesh_template_filename = nullptr

protected

Mesh template file to use for creating mesh tallies in OpenMC; currently, this mesh must be identical to the mesh used in the [Mesh] block because a simple copy transfer is used to extract the tallies and put on the application's mesh in preparation for a transfer to another MOOSE app. If not set, this indicates that tallying will be performed directly on the [Mesh]. TODO: allow the mesh to not be identical, both in terms of using different units and more general differences like not having a particular phase present

The translation to apply to the mesh template.
