Solution of incompressible flow using FEM adjusted to singularity
Šístek, J. ; Burda, P. ; Novotný, Jaroslav
We describe solution of incompressible fluid flow using the finite element method on meshes adjusted to singularity.
Experimental aeroelastic investigation of models with one- and two degrees of freedom
Vlček, Václav ; Luxa, Martin
Two models for aeroelastic experiments were realized and partly tested. Models have one- and two-degrees of freedom, elastic properties of these models are changeable. It is possible to carry out simultaneous optical measurements of the flow field and dynamic measurements.
Fluid flow along the airfoil at high Reynolds numbers solved by means of the finite element method
Damašek, Alexandr ; Burda, Pavel
The paper deals with solution of Navier-Stokes equations for higher Reynolds numbers using the SUPG method. Results are shown on an example of fluid along the profile.
Parallelization of direct methods for solution of large systems of linear equations
Novotný, Jaroslav ; Burda, P.
We study parallelization of direct methods on shared and distributed memory computers using OpenMP and MPI. We describe parallelization of Gaussian elimination using OpenMP and several versions of parallelization using MPI. We also describe parallelization of frontal method.
Numerical solution of flow past an oscillating profile in a channel
Honzátko, R. ; Horáček, Jaromír ; Kozel, K.
The paper presents the numerical solution of 2D flow for inviscid incompressible fluid in a channel with a profile inside. The fluid flow is modified by a prescribed oscillation of the profile. The Euler equations are used for the fluid flow and the motion of the profile is given by a harmonic time varying angle of attack.
Paralelizace algoritmu BICG-STAB pro výpočty metodou konečných prvků
Sousedík, B. ; Novotný, Jaroslav
We present results of parallelization of BICG-STAB method for finite element computations using element by element strategy both on distributed and shared parallel architectures.
Aplikace apriorních odhadů chyby pro metodu konečných prvků pro zjemnění sítě poblíž singularity v proudění vazké nestlačitelné tekutiny
Šístek, J. ; Burda, P. ; Novotný, Jaroslav
In the paper we describe application of apriori error estimates for generation of finite element mesh near singularity for accurate solution of the Navier-Stokes equations.
