Constructor.

Scans the mesh and sets the cells in the mesh active and the level of refinement in all cells to the given values. rebuild_ is set to true, ie. if the mesh is used it will firstly be rebuilt.

Parameters

msh	The surface of interest partitioned into a mesh.
lvl	Level of refinement

template<class F = concepts::Real>

void bem::AdaptConst3d000< F >::adjust	(	const concepts::Element< F > &	elm,
		const AdaptiveAdjust &	a
	)

Sets the adjustments for an element.

The adjustment information in adj_ is updated and the flag rebuild_ is set to true.

Parameters

elm	Element to be adjusted
l	Difference in the level

Exceptions

◆ adjust() [2/3]

template<class F = concepts::Real>

void bem::AdaptConst3d000< F >::adjust	(	const Constant3d001< F > &	elm,
		const AdaptiveAdjust &	a
	)

◆ adjust() [3/3]

virtual void concepts::AdaptiveSpace< concepts::Real , AdaptiveAdjust >::adjust	(	const Element< concepts::Real > &	elm,
		const AdaptiveAdjust &	a
	)

pure virtualinherited

Adjusts the space in the next rebuild step for this element.

◆ dim() [1/2]

template<class F >

uint bem::AdaptConst3d000< F >::dim

inlinevirtual

Returns the dimension of the space.

Implements concepts::SpaceOnCells< concepts::Real >.

Definition at line 359 of file space.hh.

◆ dim() [2/2]

template<class F >

uint bem::AdaptConst3d000< F >::dim

inline

Returns the number of degrees of freedom.

Exceptions

SpaceNotBuilt

Definition at line 353 of file space.hh.

◆ getOutputDimension()

virtual uint concepts::Space< concepts::Real >::getOutputDimension ( ) const

inlinevirtualinherited

Returns the default output dimension, when we consider plotting a real-valued operator on this space.

Definition at line 50 of file space.hh.

◆ info() [1/2]

template<class F = concepts::Real>

std::ostream& bem::AdaptConst3d000< F >::info ( std::ostream & os ) const

inlineprotectedvirtual

Reimplemented from concepts::SpaceOnCells< concepts::Real >.

Definition at line 287 of file space.hh.

◆ info() [2/2]

template<class F = concepts::Real>

std::ostream& bem::AdaptConst3d000< F >::info	(	std::ostream &	os,
		uint	mode = `0`
	)		const

Gives some information about the space.

Exceptions

SpaceNotBuilt

Parameters

os	Output stream
mode	There are different levels of information available. mode = 0 Output of dimension and number of elements mode = 1 Prints all elements

◆ l()

template<class F = concepts::Real>

short bem::AdaptConst3d000< F >::l ( Constant3d001< F > & elm )

inline

Returns the level of a element.

Definition at line 320 of file space.hh.

◆ maxlevel()

template<class F >

uint bem::AdaptConst3d000< F >::maxlevel

inline

Returns the maximal level of all elements.

Definition at line 377 of file space.hh.

◆ minlevel()

template<class F >

uint bem::AdaptConst3d000< F >::minlevel

inline

Returns the minimal level of all elements.

Definition at line 383 of file space.hh.

◆ nelm() [1/2]

template<class F >

uint bem::AdaptConst3d000< F >::nelm

inlinevirtual

Returns the number of elements in the space.

Implements concepts::SpaceOnCells< concepts::Real >.

Definition at line 371 of file space.hh.

◆ nelm() [2/2]

template<class F >

uint bem::AdaptConst3d000< F >::nelm

inline

Returns the number of elements of the space.

Exceptions

SpaceNotBuilt

Definition at line 365 of file space.hh.

◆ rebuild()

template<class F = concepts::Real>

void bem::AdaptConst3d000< F >::rebuild ( )

Rebuilds the space.

First the old list of elements in the space is removed (not the elements in the topology!). For every cell in the original mesh, rebuild0_ and rebuild1_ are called. From the mesh, they build the space and store the elements in elm_. rebuild0_ marks the elements with the right values and rebuild1_ really does the work.

Exceptions

MissingFeature

◆ rebuild0_()

template<class F = concepts::Real>

void bem::AdaptConst3d000< F >::rebuild0_	(	concepts::Connector2 &	cntr,
		int	l,
		int &	L
	)

private

Marks the cells correctly for the new space.

First, the desired level in the current connector is determined. Second, the maximum desired level of the children is recursively determined, if we need to refine the current connector. Third, the tag of the current connector is updated.

Parameters

cntr	The current connector (part of the topology)
l	The current level
L	The desired level

◆ rebuild1_()
