  abstract = {Most finite element, or finite volume software is built around a fixed
	mesh data structure. Therefore, each software package can only be
	used efficiently for a relatively narrow class of applications. For
	example, implementations supporting unstructured meshes allow the
	approximation of complex geometries but are in gen- eral much slower
	and require more memory than implementations using structured meshes.
	In this paper we show how a generic mesh interface can be defined
	such that one algorithm, e. g. a discretization scheme, works on
	different mesh implementa- tions. For a cell centered finite volume
	scheme we show that the same algorithm runs thirty times faster on
	a structured mesh implementation than on an unstruc- tured mesh and
	is only four times slower than a non-generic version for a structured
	mesh. The generic mesh interface is realized within the Distributed
	Unified Numerics Environment DUNE.},
