Detailed Description

The base class for all remeshing criteria. The basic task is to evaluate the required mesh density (at nodes) on given domain, based on informations provided by the compatible error estimator. If this task requires the special element algorithms, these should be included using interface concept.

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.

Member Function Documentation

◆ estimateMeshDensities()

virtual int oofem::RemeshingCriteria::estimateMeshDensities ( TimeStep * tStep )

pure virtual

Estimates the nodal densities.

Parameters

tStep Time step.

Implemented in oofem::CombinedZZSIRemeshingCriteria, oofem::DirectErrorIndicatorRC, oofem::HuertaRemeshingCriteria, and oofem::ZZRemeshingCriteria.

◆ giveDofManDensity()

virtual double oofem::RemeshingCriteria::giveDofManDensity ( int num )

pure virtual

Returns existing mesh size for given dof manager.

Parameters

num	DofMan number.

Implemented in oofem::CombinedZZSIRemeshingCriteria, oofem::DirectErrorIndicatorRC, oofem::HuertaRemeshingCriteria, and oofem::ZZRemeshingCriteria.

◆ giveRemeshingStrategy()

virtual RemeshingStrategy oofem::RemeshingCriteria::giveRemeshingStrategy ( TimeStep * tStep )

pure virtual

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

Parameters

tStep Time step.

Implemented in oofem::CombinedZZSIRemeshingCriteria, oofem::DirectErrorIndicatorRC, oofem::HuertaRemeshingCriteria, and oofem::ZZRemeshingCriteria.

◆ giveRequiredDofManDensity()

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

pure virtual

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
