Detailed Description

Carries out a-priori given refinements.

The mesh is geometrically refined towards the given vertices or edges. These can be determined by their attribute. If a refinement in one direction occurs, p is not increased in this direction. Otherwise it is increased by the given amount. This makes it possible to generate geometrically refined meshes to corners and edges with linear polynomial degree distribution.

Currently, methods for hp2D::Quad are implemented.

Author:: Philipp Frauenfelder, 2003

Bug:: The parameter p of the constructor can be set to a pointer to 0. This is not detected and a run-time error occurs.

Examples:: hpFEM2d-simple.cc, and hpFEM2d.cc.

Constructor & Destructor Documentation

hp2D::APrioriRefinement::APrioriRefinement	(	concepts::AdaptiveSpace< Real, concepts::AdaptiveAdjustP< 2 > > &	spc,
		concepts::Attribute	attribVtx,
		concepts::Attribute	attribEdge,
		const int *const	p,
		const uint	subdiv = `X \| Y`,
		const concepts::Attribute	attribCell = `0`
	)		`[inline]`

Constructor for refining an adaptive space.

If a given attribute for the vertices or edges is 0, it is not considered.

Parameters:

spc	Space to be refined
attribVtx	Refine towards vertices with this attribute
attribEdge	Refine towards edges with this attribute
p	If there is no refinement, p will be increased by this amount (anisotropically)
subdiv	possibility to restrict subdivision strategy
attribCell	possibility to restrict subdivision to particular cells

		concepts::Attribute	attribVtx,
		concepts::Attribute	attribEdge,
		const int *const	p,
		const uint	subdiv = `X \| Y`
	)		`[inline]`

Constructor for refining a space pre builder.

The global post process has to be given the mesh, so that the ()-operator for cells is called.

If a given attribute for the vertices or edges is 0, it is not considered.

Parameters:

adj	Space Pre Builder to be refined
attribVtx	Refine towards vertices with this attribute
attribEdge	Refine towards edges with this attribute
p	If there is no refinement, p will be increased by this amount (anisotropically)
subdiv	possibility to restrict subdivision strategy
