Description	The BDDC method (Balanced Domain Decomposition by Constraints) is a recent method for solving large sparse ill-conditioned linear systems which arise at numerical solution of differencial equations. This method belongs to leading algorithms in the field of unstructured meshes decomposition and it has been shown in several studies that it posseses very good convergence properties. We have developed a parallel finite element solver based on the BDDC method and we have got some promising results on real problems of linear elasticity.

(en) Metoda BDDC (Balanced Domain Decomposition by Constraints) je jedna z nových metod pro řešení velkých řídkých špatně podmíněných lineárních soustav, které vznikají při numerickém řešení diferenciálních rovnic. Jde o metodu rozkladu oblasti, která patří mezi nejlepší současné algoritmy tohoto typu a je podložena solidní matematickou teorií včetně důkazu dobrých konvergenčních vlastností. Vyvinuli jsme paralelní program pro použití metody BDDC pro řešení úloh diskretizovaných metodou konečných prvků a získali jsme slibné výsledky při řešení velkých úloh lineární elasticity pocházejících z praxe.
