Space-time discontinuous Galerkin method for the compressible Navier-Stokes equations

A space-time discontinuous Galerkin finite element method for the compressible Navier-Stokes equations is presented. We explain the space-time setting, derive the weak formulation and discuss our choices for the numerical fluxes. The resulting numerical method allows local grid adaptation as well as moving and deforming boundaries, which we illustrate by computing the flow around a 3D delta win...

Mid - Year Report Discontinuous Galerkin Euler Equation Solver

The focus of this effort is to produce a two dimensional inviscid, compressible flow solver using the Discontinuous Galerkin Finite Element approach. The Discontinuous Galerkin method seeks to project the exact solution onto a finite polynomial space while allowing for discontinuities at cell interfaces. This allows for the natural discontinuity capture that is required for a compressible flow ...

General element shapes within a tensor-product higher-order space-time discontinuous-Galerkin formulation

A tensor-product higher-order space-time discontinuous-Galerkin method is extended to unstructured element shapes. The use of a tensor-product formulation is key to maintaining efficiency at high polynomial orders. The discrete system of equations arising at each space-time slab is solved using a Jacobian-free Newton-Krylov scheme. An alternatingdirection-implicit (ADI) preconditioner for hexah...

Discontinuous Galerkin solution of compressible flow in time-dependent domains

This work is concerned with the simulation of inviscid compressible flow in time dependent domains. We present an ALE (Arbitrary Lagrangian-Eulerian) formulation of the Euler equations describing compressible flow, discretize them in space by the discontinous Galerkin method and introduce a semi-implicit linearized time stepping for the numerical solution of the complete problem. Special attent...

On Numerical Solution of Compressible Flow in Time-dependent Domains

The paper deals with numerical simulation of a compressible flow in timedependent 2D domains with a special interest in medical applications to airflow in the human vocal tract. The mathematical model of this process is described by the compressible Navier-Stokes equations. For the treatment of the time-dependent domain, the arbitrary Lagrangian-Eulerian (ALE) method is used. The discontinuous ...
