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.

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

APrioriRefinement() [1/3]

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

APrioriRefinement() [2/3]

hp2D::APrioriRefinement::APrioriRefinement ( concepts::AdaptiveSpace< Real, concepts::AdaptiveAdjustP< 2 > > &  spc, const int *const  p, const uint  subdiv = X | Y, const concepts::Level< 2 >  level = MAXSHORT  )

inline

Definition at line 66 of file aprioriRef2D.hh.

APrioriRefinement() [3/3]

hp2D::APrioriRefinement::APrioriRefinement ( concepts::Adaptivity< concepts::Connector, concepts::AdaptiveAdjustP< 2 > > &  adj, 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
