Nedávný pohled na metodu BDDC a její paralelní implementaci
Šístek, Jakub ; Sousedík, Bedřich ; Čertíková, Marta ; Burda, P. ; Neumanová, E. ; Novotný, Jaroslav ; Damašek, Alexandr
A new view at the BDDC method was presented. Parallel implementation is described. Numerical results show effectiveness of the method.
Metoda konečných prvků pro Navierovy-Stokesovy rovnice v některých problémech nestlačitelného proudění
Burda, P. ; Novotný, Jaroslav ; Šístek, Jakub
We deal with 2D flows of incompressible viscous fluid modelled by the Navier-Stokes equations. We focus on reliable modelling of flows in channels or tubes with abrupt changes of the diameter. We present two techniques: one is based on aposteriori error estimates and adaptivity, second makes use of the apriori error estimates and asymptotic behaviour of the solution near the corners.

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.
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.
