Detailed Description

The implementation of combined criteria: Zienkiewicz Zhu Error Estimator for elastic regime and scalar error indicator in non-linear regime. The basic task is to evaluate the stress error on associated domain. The algorithm is written in general way, so it is possible to to evaluate different errors (for example temperature error). Then corresponding member attribute identifying the type of quantity used should be declared and initialized (for example in instanciateYourself() service). Then the modification is required only when requesting element contributions.

Member Function Documentation

◆ estimateError()

int oofem::CombinedZZSIErrorEstimator::estimateError	(	EE_ErrorMode	mode,
		TimeStep *	tStep )

overridevirtual

Estimates the error on associated domain at given time step. The estimated values can be requested using giveElementError and giveValue methods. The type of errors provided depends on error estimator type implementing the service.

Parameters

mode	Error mode.
tStep	Time step.

Implements oofem::ErrorEstimator.

◆ giveClassName()

const char * oofem::CombinedZZSIErrorEstimator::giveClassName ( ) const

inlineoverridevirtual

Returns: Class name of the receiver.

◆ giveElementError()

double oofem::CombinedZZSIErrorEstimator::giveElementError	(	EE_ErrorType	type,
		Element *	elem,
		TimeStep *	tStep )

overridevirtual

Returns the element error. The estimateError service should be called before.

Parameters

type	Error type.
elem	Element for which error requested.
tStep	Time step.

Returns: Element error.

Implements oofem::ErrorEstimator.

◆ giveInputRecordName()

const char * oofem::CombinedZZSIErrorEstimator::giveInputRecordName ( ) const

inlineoverridevirtual

Returns: Input record name of the receiver.

◆ giveRemeshingCrit()

RemeshingCriteria * oofem::CombinedZZSIErrorEstimator::giveRemeshingCrit ( )

overridevirtual

Returns reference to associated remeshing criteria.

Implements oofem::ErrorEstimator.

Referenced by initializeFrom(), and setDomain().

◆ giveValue()

double oofem::CombinedZZSIErrorEstimator::giveValue	(	EE_ValueType	type,
		TimeStep *	tStep )

overridevirtual

Returns the characteristic value of given type. The estimateError service should be called before. This method is supposed to be used by associated remeshingCriteria to access some characteristic values already computed or known at error estimator level.

Parameters

type	Error type.
tStep	Time step.

Returns: Error value for given type.

Implements oofem::ErrorEstimator.

Definition at line 78 of file combinedzzsiee.C.

◆ initializeFrom()

void oofem::CombinedZZSIErrorEstimator::initializeFrom ( InputRecord & ir )

overridevirtual

Initializes receiver according to object description stored in input record. This function is called immediately after creating object using constructor. Input record can be imagined as data record in component database belonging to receiver. Receiver may use value-name extracting functions to extract particular field from record. Note that initializeFrom may be called mutiple times.

See also: IR_GIVE_FIELD; IR_GIVE_OPTIONAL_FIELD

Parameters

ir	Input record to initialize from.
priority	Priority of the input record. This is used to determine the order of initialization

◆ setDomain()

void oofem::CombinedZZSIErrorEstimator::setDomain ( Domain * d )

overridevirtual

Sets associated Domain

Parameters

d	New domain which receiver should belong to.
