Detailed Description

Carries out a-priori given refinements.

The mesh is geometrically refined towards the given vertices, edges or faces. 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 hp3D::Hexahedron 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:

hpFEM3d-EV.cc.

Constructor & Destructor Documentation

hp3D::APrioriRefinement::APrioriRefinement	(	concepts::AdaptiveSpace< Real, concepts::AdaptiveAdjustP< 3 > > &	spc,
		concepts::Attribute	attribVtx,
		concepts::Attribute	attribEdge,
		concepts::Attribute	attribFace,
		const int *const	p
	)		[inline]

Constructor.

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
attribFace	Refine towards faces with this attribute
p	If there is no refinement, p will be increased by this amount (anisotropically)
