Description
  • Článek popisuje metody rozložení oblasti Schwarzova typu s hrubými problémy konstruovanými algebraicky agregací neznámých. Popis obsahuje také novou metodu bez překrytí podoblastí a rozhraní na hrubé síti. U všech metod se diskutují implementační záležitosti a na modelovém příkladu z pružnosti se dělá jejich porovnání. Zvláštní pozornost je věnována nesymetrickým hybridním předpodmiňovačům. Paralelní implementace aditivní Schwarzovy metody se testuje na 3D problému pružnosti s využitím výpočetního klastru typu Beowulf. (cs)
  • The paper describes domain decomposition methods of the Schwarz type with coarse problems constructed algebraically by aggregation of inknowns. The description includes a new method with no overlap of subdomains and interfaces on the coarse grid. Implementation issues are discussed for all the methods and their comparison is made on a model elasticity problem. Special attention is given to nonsymmetric hybrid proconditioners. A parallel implementation of the additive Schwarz method is tested on a 3D elasticity problem, employing a Beowulf cluster.
