Die Filiale im Internetzeitaltertype on adaptively refined grids. Local error estimates in subdomains away from boundary and interior layers are uniformly valid with respect to the small parameter. Boundary and interior layers can be resolved using locally anisotropic mesh refinement. Numerical examples are given for scalar convec

Die Filiale im Internetzeitalterally refined grids. Our first aim is to combine modern optimal multigrid methods with the robustness strategies developed for structured grids and in the second part we discuss a parallel implementation of the programming environment on multiprocessors with distributed memory. The various techniques

The basic concepts will be introduced as a combination and generalization of the Archimedes Rule and the multi-variate extrapolation. We describe the data structures and show the a

We discuss both the approximation qualities of the adaptively generated sparse grids and the efficient iterative solution of the arising linear systems by means of certain grid- and point-oriented multilevel methods..The results of numerical experiments regarding both topics are p
