  Grid Generation and Geometry Description with COG
I. Schmelzer (WIAS Berlin)

COG is a package for 2D and 3D grid generation. It's main purpose is generation of Delaunay grids for finite volume methods. It allows local and anisotropic refinement.

A main advantage is an interface for geometry description which allows to use very different methods of geometry description (pixmaps, voxmaps, characteristic functions, elevation profiles, grids), transformations of these geometries (curvilinear coordinates, extensions into 3D, intersections with 2D planes) and boolean operations between all these geometries. This makes it easy to describe complex geometries.

We emphasize the importance of anisotropic grid generation especially in 3D and consider the problems related with generation of highly anisotropic Delaunay grids.
