A solution adaptive space-time discontinuous Galerkin method for the compressible Navier-Stokes equations

Activity: Talk or presentationOral presentation

Description

In this presentation an overview will be given of a space-time discontinuous Galerkin finite element method for the compressible Navier-Stokes equations. The formulation of the equations in the space-time setting will be explained, which will be used to derive the discontinuous Galerkin formulation. Special attention will be given to a discussion of the different choices for the numerical fluxes and the use of a pseudo-time stepping method to solve the large number of algebraic equations resulting from the space-time discretization efficiently. The numerical method allows local grid adaptation as well as moving and deforming meshes, which we illustrate by computing the flow around a 3D delta wing on an adapted mesh and by simulating the dynamic stall phenomenon of a 2D airfoil in rapid pitch up maneuver.
