Detailed Description

A projection-based selector for H1 space.

This class is designed to be used with the class H1Adapt. Since an initialization of the class may take a long time, it is suggested to create the instance outside the adaptivity loop.

Member Enumeration Documentation

enum RefinementSelectors::H1ProjBasedSelector::LocalFuncExpansion [protected]

A function expansion of a function f used by this selector.

Enumerator:

H2D_H1FE_VALUE	A function expansion: f.
H2D_H1FE_DX	A function expansion: df/dx.
H2D_H1FE_DY	A function expansion: df/dy.
H2D_H1FE_NUM	A total considered function expansion.

Constructor & Destructor Documentation

RefinementSelectors::H1ProjBasedSelector::H1ProjBasedSelector	(	CandList	cand_list = `H2D_HP_ANISO`,
		double	conv_exp = `1.0`,
		int	max_order = `H2DRS_DEFAULT_ORDER`,
		H1Shapeset *	user_shapeset = `NULL`
	)

Constructor.

Parameters:

`[in]`	cand_list	A predefined list of candidates.
`[in]`	conv_exp	A conversion exponent, see evaluate_cands_score().
`[in]`	max_order	A maximum order which considered. If H2DRS_DEFAULT_ORDER, a maximum order supported by the selector is used, see HcurlProjBasedSelector::H2DRS_MAX_H1_ORDER.
`[in]`	user_shapeset	A shapeset. If NULL, it will use internal instance of the class H1Shapeset.
