	Vývoj efektivního paralelního BDDC řešiče pro úlohy lineární pružnosti Šístek, Jakub ; Čertíková, Marta ; Burda, P. ; Neumanová, E. ; Pták, Svatopluk ; Novotný, Jaroslav ; Damašek, Alexandr Our goal is to develop an efficient implementation of the BDDC method, which could be used fo solution of large problems of today's computational mechanics and structural analysis. A parallel approach is necessary for the usage of powerfull computer resources. We present results of computations of practical problems in 3D elasticty. Detailed record
	Aplikace metody dekompozice domén BDDC na výpočet napětí v konstrukcích Šístek, Jakub ; Čertíková, Marta ; Novotný, Jaroslav ; Burda, P. ; Damašek, Alexandr We deal with the Balancing domain decomposition with constraints method (BDDC) applied to 3D elasticity. Theoretical framework is recalled in the first part. The second part describes implementation of the method on parallel computers. Several numerical results of practical problems of structural analysis are presented. Detailed record

	Aplikace apriorních a aposteriorních odhadů chyb k dosažení přesného řešení nestlačitelného proudění pomocí MKP Burda, P. ; Novotný, Jaroslav ; Šístek, J. One of the open problems in fluid dynamics we deal with is reliable modelling of flows in channels with abrupt changes of the diameter. The goal of this work is to construct the FEM solution in the vicinity of these corners as precise as desired. The first approach makes use of aposteriori error estimates of the FEM solution. The second approach uses the aprriori error estimate of the FEM solution based on estimation of the seminorm of the exact solution by means of the asymptotic behaviour of the exact solution of the NSE in the vicinity of the corner. Numerical results are demonstrated on two examples. Detailed record
	Aplikace metody BDDC v úlohách lineární elasticity Burda, P. ; Čertíková, M. ; Damašek, Alexandr ; Neumanová, E. ; Novotný, Jaroslav ; Šístek, J. Balancing Domain Decomposition with Constrained Energy Minimization (BDDC) derives benefit from the synergy effect between substructuring methods and multigrid approaches to preconditioning. It has been shown in several studies, that this method posseses very good properties and is competitive with FETI and FETI-DP methods, which could be mentioned among leading algorithms in the field of unstructured meshes decomposition for solving partial differential equations.
