Analytical solution of Stokes flow near corners and applications to numerical solution of Navier-Stokes equations with high precision
Burda, P. ; Novotný, Jaroslav ; Šístek, Jakub
We present analytical solution of the Stokes problem in 2D domains. This is then used to find the asymptotic behavior of the solution in the vicinity of corners, also for Navier-Stokes equations in 2D. We apply this to construct very precise numerical finite element solution.
Application of the BDDC method to the Stokes problem
Šístek, Jakub ; Burda, P. ; Mandel, J. ; Novotný, J. ; Sousedík, B.
Application of BDDC method to problems of Stokes flow is explored. BDDC is applied to several 3D problems and is shown to be a competitive method.
Adaptive mesh refinement versus refinement adjusted to singularity in 2D flow problem
Burda, P. ; Novotný, Jaroslav ; Jelínek, M. ; Sousedík, B.
We describe adaptive mesh refinement based on aposteriori error estimates for the Stokes flow in a 2D problem.
A posteriori error estimates for the Stokes flow
Burda, P. ; Beneš, V. ; Novotný, Jaroslav
A posteriori error estimates for the Stokes flow in 2D polygonal domain are discussed.
Towards adaptive mesh refinement based on a posteriori error estimates for the Stokes flow
Burda, P. ; Novotný, Jaroslav ; Sousedík, B.
A posteriori error estimates for the Stokes problem on 2D domain are investigated. Hood-Taylor finite elements are used.
