Numerical simulation of incompressible fluid flow with the help of isogeometric analysis

Abstract: Isogeometric analysis is a relatively recently introduced concept for numerical solving of partial differential equations which bridges the gap between geometric modelling and numerical simulation/analysis.

In this talk, the isogeometric analysis is used for numerical simulation of incompressible fluid flow. We give an overview of the method which shares many features with Finite Element Method, but different meshes and basis functions also lead to significant differences. We present advantages and drawbacks of the method which we have encountered during development of incompressible turbulent flow solver and we focus on our results concerning isogeometric mesh generation, stabilization methods and solving systems of linear equations in this context.
