Detailed Description

The class representing Huerta remeshing criteria. The basic task is to evaluate the required mesh density (at nodes) on given domain, based on information provided by the compatible error estimator.

The remeshing criteria is maintained by the corresponding error estimator. This is mainly due to fact, that is necessary for given EE to create compatible RC. In our concept, the EE is responsible.

◆ giveDofManDensity()

double oofem::HuertaRemeshingCriteria::giveDofManDensity ( int num )

overridevirtual

Returns existing mesh size for given dof manager.

Parameters

num	DofMan number.

Definition at line 323 of file huertaerrorestimator.h.

◆ giveRemeshingStrategy()

RemeshingStrategy oofem::HuertaRemeshingCriteria::giveRemeshingStrategy ( TimeStep * tStep )

overridevirtual

Determines, if the remeshing is needed, and if needed, the type of strategy used.

Parameters

tStep Time step.

Implements oofem::RemeshingCriteria.

References estimateMeshDensities(), and remeshingStrategy.

◆ giveRequiredDofManDensity()

double oofem::HuertaRemeshingCriteria::giveRequiredDofManDensity	(	int	num,
		TimeStep *	tStep,
		int	relative = 0 )

overridevirtual

Returns the required mesh size n given dof manager. The mesh density is defined as a required element size (in 1D the element length, in 2D the square from element area).

Parameters

num	Dofman number.
tStep	Time step.
relative	If zero, then actual density is returned, otherwise the relative density to current is returned.

◆ initializeFrom()

void oofem::HuertaRemeshingCriteria::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

Reimplemented from oofem::FEMComponent.
