Conventional software engineering concepts do not provide a sufficient basis for the implementation of general, fast, and robust multilevel applications. In particular, there is a severe tradeoff between the generality of such software and its efficiency. These problems can be alleviated on the basis of a consequent data abstraction. To equally satisfy the demands for generality and efficiency it is necessary to introduce a two level software model based on a generation and an execution phase. Suitable implementation techniques are discussed.", editors = "S. Hengst", } @Unpublished{Ruede:1993:EEB, author = "U.

The subspaces in such a splitting and their Hilbert space structure define elementary operations, called subspace corrections which can in turn be used to construct iterative methods and preconditioners. In this general setup many solution methods can be described, including classical relaxation schemes and domain decomposition algorithms. We are particularly interested in the special case of (variational) multigrid methods, based on a nested system of subspaces and the multiplicative combination of the subspace corrections, or the corresponding additive methods that lead to efficient preconditioners. The discussion of methods in this setup turns out to be useful, because the performance of solvers and preconditioners can be described by abstract features of the subspace system. The stability of the splitting has been introduced as the basic property that determines the efficiency of the corresponding methods. Furthermore, however, the splitting of the space can be used to derive error estimators. If the splitting is stable, the lower and upper bounds obtained for the error are uniformly bounded. Depending on the interpretation of the spaces, the bounds apply to the (algebraic) iteration error or the (continuous) discretization error. In any case, the estimate is based on subspace corrections, as they are computed in each iteration step. Therefore the error estimate does not create any additional cost. In the paper we review the theory of stable splittings and the derivation of the abstract error estimates. Furthermore we discuss their performance in realistic algorithms and their efficient integration with the multilevel adaptive iteration and the virtual global mesh refinement technique to a fully adaptive multilevel technique for the solution of partial differential equations.", } @TechReport{Ruede:1993:ETC, author = "U.

In contrast to conventional extrapolation methods for elliptic equations these results use only a local analysis and can thus be used on unstructured meshes.

For the optimal solution of PDEs, however, the quality of the discretization is of the same importance as the speed of the algebraic solution process. Especially for high accuracy requirements, high order discretizations become increasingly attractive. We describe higher order techniques, like extrapolation and sparse grid combination that are particularly interesting in the context of multilevel algorithms, because they are based on discretizing the problems on grids with different mesh sizes. Classical Richardson extrapolation can be extended and generalized in many ways. One generalization is to consider the mesh widths in the different coordinate directions as distinct parameters.
