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.

num DofMan number.
Implemented in oofem::HuertaRemeshingCriteria, oofem::ZZRemeshingCriteria, oofem::CombinedZZSIRemeshingCriteria, and oofem::DirectErrorIndicatorRC.
|
pure virtual |
Determines, if the remeshing is needed, and if needed, the type of strategy used.
- Parameters
-
tStep Time step.
Implemented in oofem::HuertaRemeshingCriteria, oofem::ZZRemeshingCriteria, oofem::CombinedZZSIRemeshingCriteria, and oofem::DirectErrorIndicatorRC.
Referenced by oofem::AdaptiveNonLinearStatic::solveYourselfAt(), and oofem::AdaptiveLinearStatic::updateYourself().
|
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
-
num Dofman number. tStep Time step. relative If zero, then actual density is returned, otherwise the relative density to current is returned.
