Approaches to parallel implementation of the BDDC method
Šístek, Jakub; Burda, P.; Čertíková, M.; Novotný, J.
2010 - anglický
During past several years, we have implemented and tested various approaches to domain decomposition methods, especially the Balancing Domain Decomposition Method by Constraints (BDDC). The goal of this paper is to summarize our experience with parallel implementation of such algorithms and to suggest ways to an implementation of the BDDC method that would be efficient on very large number of cores of computers of near future.

A survey of global investigations of linear differential equations
Neuman, František
2010 - anglický
In contrast to the local investigations of behavior of solutions of linear differential equations, that started already in the XVII-th century, here we present a survey of methods and results of a global nature. It was possible to establish the unified theory of global properties of solutions of linear differential equations: to describe global canonical forms, distribution of zeros of solutions and other global properties of the equations studied.

Some remarks on averaging in the BDDC method
Čertíková, M.; Burda, P.; Novotný, J.; Šístek, Jakub
2010 - anglický
In this paper, we introduce a general framework for derivation of the averaging operator, from hich the standard choices are recovered by simplifications. Then, an alternative approach derived by another simplification is proposed and tested on a 2D example.

Integration in higher-order finite element method in 3D
Kůs, Pavel
2010 - anglický
Integration of higher-order basis functions is an important issue, that is not as straightforward as it may seem. In traditional low-order FEM codes, the bulk of computational time is a solution of resulting system of linear equations. In the case of higher-order elements the situation is different. Especially in three dimensions the time of integration may represent significant part of the computation.

Complementarity - the way towards guaranteed error estimates
Vejchodský, Tomáš
2010 - anglický
This paper presents a review of the complementary technique with the emphasis on computable and guaranteed upper bounds of the approximation error. For simplicity, the approach is described on a numerical solution of the Poisson problem. We derive the complementary error bounds, prove their fundamentals properties, present the method of hypercircle, mention possible generalizations and show a couple of numerical examples.

On selections of constraints for the BDDC method
Čertíková, M.; Šístek, Jakub; Novotný, J.; Burda, P.
2010 - anglický
The Balancing Domain Decomposition by Constraints (BDDC) method is an iterative substructuring domain decomposition method which uses a coarse space. The choice of coarse constraints on continuity has strong influence on convergence of the method. The goal of this paper is to compare the performance of several algorithms for selection of the coarse constraints applied to both test and industrial 3D linear elasticity problems and confront results obtained for typical test problems with results for industrial problems.
