Index of the GrAL Triang2D Grid Module

This module contains the concrete grid component Triang2D. An object of type Triang2D represents a two-dimensional triangulation. The only incidence relation stored is cell-vertex incidence, in a simple integer array.

The module also serves as an example how to adapt a given ``classical'' grid data structure to the GrAL interface. Therefore, most things are kept simple, even if much shorter implementations would be possible by reusing generic components e.g. for defining iterators.

The main classes one might use are: (headers under the path Gral/Grids/Triang2D)

• Triang2D (triang2d.h): The combinatorial grid
• total grid function (see TotalGridFunction concept, grid-functions.h)
• partial grid functions (see PartialGridFunction concept, partial-grid-functions.h )
• ConstructGrid0(Triang2D,...) for copying an arbitrary grid into a Triang2D grid (construct.h)
• stored_geometry_Triang2D for a simple geometry (see VertexGridGeometry concept)
• all.h for all of the above.

Status:

• switch operators have to be defined (for edges and vertices)
