An application of parallel DiD and DD solvers
Blaheta, Radim ; Jakl, Ondřej ; Krečmer, Karel ; Starý, Jiří
The paper describes solution of large scale linear systems arising from finite element analysis by parallel solvers, which use decomposition ideas. Namely, Displacement Decomposition and Domain Decomposition techniques are discussed.
Numerical Analysis. Proceedings of the seminar dedicated to the jubilee of Ivo Marek
Blaheta, Radim ; Starý, Jiří
This proceedings contains the extended abstracts of the contributions delivered at the Seminar on Numerical Analysis, held at the Institute of Geonics AS CR Ostrava. The scope of the seminar includes study of algorithms for the solution of problems of continuous mathematics, algorithms of numerical linear algebra and application of the numerical methods in mathematical modelling.
Large Scale modelling in geomechanics: elasticity, thermo-elasticity and iterative solvers
Blaheta, Radim ; Byczanski, Petr ; Starý, Jiří
Mathematical modelling of many geomechanical problems with the aid of the finite element method leads to high computational demands, which are concentrated in the solution of large-scale linear systems. This contribution adresses the solution of these systems by iterative methods based on CG and its generalizations, the use of space decomposition preconditioners and good initial guesses in a time stepping procedure.
