Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A progressive research in domain decomposition in the last several decades has been motivated by inceasing availability of multicore, parallel computers. In this contribution we focus on an iterative substructuring class of the domain decomposition methods. Some of the most popular methods are formulated under so-called minimalist assumptions. This allows for their effective comparison, which reveales that some of the methods are equivalent or even the same. Finally, the theory is used to develop an adaptive method that significantly improves convergence of two most advanced methods, BDDC and FETI-DP. 76 pp. Englisch.…

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The Balancing Domain Decomposition by Constraints (BDDC) method by Dohrmann (2003) is one of the the most advanced method from the Balancing family of iterative substructuring methods by Mandel (1993). In the first part we formulate a new family of abstract Multispace BDDC methods and give condition number bound from the abstract additive Schwarz preconditioning theory. The Multilevel BDDC is then treated as a special case of the Multispace BDDC. In the second part we propose a method for adaptive selection of the coarse space for the original two-level BDDC method. The method works by adding coarse degrees of freedom constructed from eigenvectors associated with intersections of selected pairs of adjacent substructures. In the third part we combine the advantages of both approaches to propose a new method called Adaptive -- Multilevel BDDC that preserves both, parallel scalability with increasing number of subdomains and also very good convergence properties. Performance of the method is illustrated by several numerical examples in two and three spatial dimensions.…
