Member Enumeration Documentation

SortOrder

template<class GridView >

enum Kaskade::EntityNumbering::SortOrder

Defines the available orderings.

Todo:

shall this be extendable by deriving from the class, or by policies, or ...?

Enumerator
SORTBYCODIM	sorts cells first, then faces, edges, and vertices last
SEQUENTIAL	sorts cells according to the cell iterator of the grid view, and places lower codim entities close to incident cells This provides very good locality of access for all algorithms that step through the cells of the grid view. Depending on the grid implementation, it does not mean that stiffness matrices have a small band width. NOT YET IMPLEMENTED
CUTHILLMCKEE	sorts all entities according to their adjacency by Cuthill-McKee This provides small bandwidth of stiffness matrices and hence good locality of access in matrix-vector products. NOT YET IMPLEMENTED
