Paralelní počítání termoelastického modelu KBS
Starý, Jiří ; Kohut, Roman
The paper describes numerical experiments with a finite element solution of the thermo-elasticity model KBS. Especially, it is devoted to the parallel computing of nonstacionary heat conduction problem, when the linear systems arising in each time step are solved by the overlapping domain decomposition method.
Víceúrovňové hierarchické předpodmínění (úvod do problematiky)
Blaheta, Radim ; Byczanski, Petr
The paper describes hierarchical decompositions and AMLI preconditioners, analysis of hierarchical decomposition methods through CBS constant in 2D and 3D, discusses robustness with respect to anisotropy and element shape and introduces fully algebraic AMLI with aggregation or agglomeration. Finally, the paper discusses recent results concerning algebraic theory of AMLI for nonconforming FEś.
O homogenizaci kvazilineární eliptické rovnice spojené s vedením tepla
Malík, Josef
A nonlinear problem connected with heat conductivity in the cores of large transformers is studied. The homogenization of the nonlinear problem for the quasilinear elliptic equation with periodic coeffitients is investigated.
Algebraicke predpodminovani iteracnich metod
Tůma, Miroslav
The talk explained the most important classes of algebraic preconditioning of Krylov space iterative methods. In particular, specialized techniques intended for parallel computers were summarized.
