Discontinuous Galerkin method for the simulation of 3D viscous compressible flows Martin Holik We deal with the numerical solution of the 3D compressible Navier-Stokes equations. We employ a combination of the discontinuous Galerkin finite element method for the space semi-discretization and backward difference formulae for the time discretization. Linearization of inviscid as well as viscous fluxes and an application of a suitable explicit extrapolation to nonlinear terms, lead us to a system of linear algebraic equations at each time step. We obtain an efficient numerical scheme which has a higher degree of approxiamtion with respect to the space and time coordinates. For practical computation is used C++ based program COOLFluiD which is briefly described in this paper.
