Some aspects of isogeometric analysis discretization of the incompressible fluid flow problem
Original language description
We focus on efficient numerical solution of the incompressible Navier-Stokes equations using our in-house solver based on the isogeometric analysis (IgA) approach. The IgA B-spline/NURBS discretization basis has several specific properties different from standard finite element basis, most importantly a higher interelement continuity leading to denser matrices. Our aim is also to developed efficient solver of these systems by a preconditioned Krylov subspace method. Therefore, the efficiency of the ideal and approximate versions of suitable state-of-the-art block preconditioners for the Navier-Stokes equations is also discussed.
