    Adaptive monotone multigrid methods for nonlinear variational problems
    Domain decomposition methods in science and engineering
    • Domain decomposition is an active, interdisciplinary research area that is devoted to the development, analysis and implementation of coupling and decoupling strategies in mathematics, computational science, engineering and industry. A series of international conferences starting in 1987 set the stage for the presentation of many meanwhile classical results on substructuring, block iterative methods, parallel and distributed high performance computing etc. This volume contains a selection from the papers presented at the 15th International Domain Decomposition Conference held in Berlin, Germany, July 17-25, 2003 by the world's leading experts in the field. Its special focus has been on numerical analysis, computational issues,complex heterogeneous problems, industrial problems, and software development.

      Domain decomposition methods in science and engineering
    • KlappentextA wide range of problems occuring in engineering and industry is characterized by the presence of a free (i. e. a priori unknown) boundary where the underlying physical situation is changing in a discontinuous way. Mathematically, such phenomena can be often reformulated as variational inequalities or related non-smooth minimzation problems. These research notes are devoted to a new and promising way of constructing fast solvers for the corresponding discretized problems providing globally convergent iterative schemes with (asymptotic) multigrid convergence speed. The presentation covers: physical modelling - existence and uniqueness results - finite element approximation - monotone mutligrid methods - a posteriori error estimation - adaptive mesh refinement. The numerical properties of the resulting adaptive multilevel algorithm are illustrated by typical applications, such as semiconductor device simulation or continuous casting. „... The presentation is very good motivated, short but very clear so that the book is good readable. It can be recommended for all who are teaching or researching in the field of numerical methods.“ ZAA Zeitschrift für Analysis und ihre Anwendung, Leipzig
