Detailed Description

Class representing a map of diameters of elements of a given Space.

At the moment just Straight Elements have computable diameter. To go to general curvature elements, a convex hull algorithm is needed to compute the diameter, since the diameter of a solid set is the diameter of the convex hull of this set.

The Diameter implementation is motivated by the Paper

"An hp-finite element adaptive scheme to solve the poisson problem on curved domains" by M.G. Armentano, C. Padra, M. Scheble

edge size are not exactly but 3-Point approximated.

Constructor & Destructor Documentation

CellDiameter() [1/2]

template<class F >

concepts::CellDiameter::CellDiameter	(	const concepts::SpaceOnCells< F > &	spc,
		const enum type	typ,
		bool	square = false
	)

Constructor getting a Space of Elements, i.e.

a hpAdaptiveSpace, TraceSpace, etc. creating a map of all element's keys to its diameter.

The constructor is downward compatible, e.g. a constructor call with a Space with 2D manifold cells and a enum call of 1D Manifold, creates a mapping of 1D manifolds to its diamters. This applicates when no lower dimensional Space is in hand, i.e. a TraceSpace for an AdaptiveSpace.

Parameters

spc	Space of 1D 2D or 3D ElementWithCells.
typ	typ of the diameter to be computed
square	marker that is set to true if all ElementWithCells are Squares (Cubes)

CellDiameter() [2/2]

concepts::CellDiameter::CellDiameter	(	const Cell &	cell,
		const enum type	typ,
		bool	square = false
	)

Constructor to compute diameter of type typ out of a Cell \cell.

If the Cell is squared or retangular one can use square set to true for faster evaluation.

Parameters

cell	Cell to use.
typ	enum to specificy which diameter type: edge, plane, etc.
square	flag to used with extra knowledge
