Space-time (H)DG methods for incompressible flows
In this talk I will discuss a new Discontinuous Galerkin (DG) method, namely the Hybridizable DG (HDG) method. We recently extended the HDG method to a space-time formulation allowing efficient and accurate computations on deforming grids/domains. I will start by explaining the method for the advection-diffusion equation after which I will introduce the method for the Incompressible Navier-Stokes (INS) equations. Results and efficiency of the space-time HDG method for the INS equations on deforming domains will then be compared to those of the space-time DG method. This work was in collaboration with Bernardo Cockburn (University of Minnesota) and Jaap van der Vegt (University of Twente).
