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
deltal	Maximal local level difference
deltaL	Maximal global level difference

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

◆ rebuild()

template<class F = concepts::Real>

void bem::AdaptConst3d002< 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_()

void bem::AdaptConst3d002< 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 edge $\rightarrow$ panel mapping is constructed Fourth, the level difference between the panels adjusted Fifth, 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
