Detailed Description

template<class F = Real>
class hp2D::GridInfo< F >

Class that represents grid information of a given 2d Fem space.

The class stores mappings from edges to underlying elements of the Fem space.

Class works on spaces with hanging nodes, i.e. k-irregular grids.

If a edge is regular there are at most 2 underlying elements. If a edge is irregular it has only 1 underlying element.

Addition for coarse irregular edges a mapping to keys of succussor irregular edges is stores.

This class e.g. applicates for Tracespaces in hp2D package.

Member Enumeration Documentation

Type

template<class F = Real>

enum hp2D::GridInfo::Type

Enumeration for type of grid edges regular = a regular edge, edge with two neighbouring cells, boundary edge, edge with only one active adjacent element. cIrregular = coarse irregular edge, that has successor edges that are irregular sIrregular = small irregular edge, that are successors of a coarse irregular edge. These edges have two adjacent elements, where that edge is edge of exactly of the two adjacent elements, i.e. elements have different level (size).

const CoarseToSuccessor & hp2D::GridInfo< F >::get

(

)

const

Returns a map from coarse irregular edges to sequence of keys, that represent successor (small irregular) edges in order.

Type

type

)

const

Returns a map from requested edge keys to underlying elements. Here the type of edge is specified by input type.

Parameters

type	specification for regular, coarse/successor irregular edge map
