Detailed Description

Refinement selectors allows to select a refinement according to an error of a candidate.

The error is calculate by comparing a candidate projected to a reference solution with the reference solution. All selectors has to be derived from the class Selector. An instance of a selector should be created outside the adaptivity loop in order to save initialization time.

Currently available selectors:

static selectors: Selectors that does not support a mechanism for selecting an optimal refinement from a list of refinements.
1. HOnlySelector
2. POnlySelector
optimum selectors: Selectors that are able to select a refinement from a provided list of possibilities which minimizes the error. All optimum selectors have to be derived from the class OptimumSelector.
1. H1ProjBasedSelector
2. L2ProjBasedSelector

Typedef Documentation

typedef double Hermes::Hermes2D::RefinementSelectors::CandElemProjError[H2DRS_MAX_ORDER+2][H2DRS_MAX_ORDER+2]

Error of an element of a candidate for various permutations of orders.

If not noted otherwise, the first index is the horizontal order, the second index is the vertical order. The maximum allowed order is H2DRS_MAX_ORDER + 1.

Enumeration Type Documentation

enum Hermes::Hermes2D::RefinementSelectors::CandList

Predefined list of candidates.

Enumerator
H2D_NONE	No adaptivity. (Used only in modules.)
H2D_P_ISO	P-candidates only. Hermes::Orders are modified uniformly.
H2D_P_ANISO	P-candidates only. Hermes::Orders are modified non-uniformly.
H2D_H_ISO	H-candidates only. Hermes::Orders are not modified.
H2D_H_ANISO	H- and ANISO-candidates only. Hermes::Orders are not modified.
H2D_HP_ISO	H- and P-candidates only. Hermes::Orders are modified uniformly.
H2D_HP_ANISO_H	H-, ANISO- and P-candidates. Hermes::Orders are modified uniformly.
H2D_HP_ANISO_P	H- and P-candidates only. Hermes::Orders are modified non-uniformly.
H2D_HP_ANISO	H-, ANISO- and P-candidates. Hermes::Orders are modified non-uniformly.

Definition at line 30 of file optimum_selector.h.

enum Hermes::Hermes2D::RefinementSelectors::SelOption

Options of the selector.

Enumerator
H2D_PREFER_SYMMETRIC_MESH	Prefer symmetric mesh when selection of the best candidate is done. If two or more candiates has the same score, they are skipped. This option is set by default.
H2D_APPLY_CONV_EXP_DOF	Use , where is the convergence exponent, instead of to evaluate the score in the method OptimumSelector::evaluate_cands_score(). This option is not set by default.
