Member Function Documentation

computeValue()

virtual Real ComputeDiffusionCoeffMGAux::computeValue ( )

overrideprotectedvirtual

Implements OpenMCAuxKernelTempl< ComputeValueType >.

getScore()

std::string TallyInterface::getScore ( const std::string &  score_param )

protectedinherited

Get the score given a parameter name which points to a MooseEnum parameter. This checks to ensure that the score is valid (at least one tally is accumulating it).

Parameters

[in]

score_param

the name of the input parameter holding the score

Returns

the valid score

kMean()

Real OpenMCBase::kMean ( const eigenvalue::EigenvalueEnum  estimator ) const

protectedinherited

A function which computes the mean value of \(k_{eff}\).

Parameters

[in]

estimator

type of estimator

Returns

the mean value of the k-eigenvalue

kStandardDeviation()

Real OpenMCBase::kStandardDeviation ( const eigenvalue::EigenvalueEnum  estimator ) const

protectedinherited

A function which computes the standard deviation of \(k_{eff}\).

Parameters

[in]

estimator

type of estimator

Returns

the standard deviation of the k-eigenvalue

mappedElement()

template<typename ComputeValueType >

bool OpenMCAuxKernelTempl< ComputeValueType >::mappedElement ( )

protectedinherited

Determine whether the MOOSE element maps to an OpenMC cell to make sure we don't call accessor methods that rely on valid values for the cell instance and index

Returns

whether element maps to OpenMC

stdev()

Real OpenMCBase::stdev ( const double &  mean, const double &  sum_sq, unsigned int  realizations  ) const

protectedinherited

Compute standard deviation of a variable

Parameters

[in]	mean	mean
[in]	sum_sq	sum squared
[in]	realizations	the number of realizations of the variable

Returns

standard deviation

tallyByScore()

std::string TallyInterface::tallyByScore ( const std::string &  score, const std::string &  tally_param  )

protectedinherited

Fetch a tally name by the score and the tally param in the input parameters. This checks the tally to ensure it is valid for the given score. If the parameter 'tally_param' is not valid and only one tally object accumulates 'score', this function returns the name of that tally.

Parameters

[in]	score	the score which the tally should be accumulating
[in]	tally_param	the parameter name in the input parameters for '_object' which contains the name of a tally.

Returns

the name of the tally which can be used to fetch score variables

validParams()
