NUMERICAL SIMULATION OF LID-DRIVEN CAVITY FLOW BY ISOGEOMETRIC ANALYSIS

In this paper, we present numerical results obtained by an in-house incompressible fluid flow solver based on isogeometric analysis (IgA) for the standard benchmark problem simulation – lid-driven cavity flow. The steady Navier-Stokes equations are solved in their velocity-pressure formulation and consider only inf-sup stable pairs of B-spline discretization spaces. main aim paper is to compare from our IgA-based with a package finite element method respect degrees freedom stability solution. Further, effectiveness recently introduced rIgA studied.The authors dedicate Professor K. Kozel occasion his 80th birthday.
