A fast, matrix-free implicit method has been developed to solve the three-dimensional compressible Euler and Navier-Stokes equations on unstructured meshes. An approximate system of linear equations arising from the Newton linearization is solved by the GMRES (generalized minimum residual) algorithm

In this paper we describe the foundation of a spectral/hp method suitable for simulating viscous compressible flows with shocks on standard unstructured meshes. It is based on a discontinuous Galerkin formulation for the hyperbolic contributions combined with a mixed Galerkin formulation for the dif
A new discretization method for the three-dimensional Euler equations of gas dynamics is presented, which is based on the discontinuous Galerkin finite element method. Special attention is paid to an efficient implementation of the discontinuous Galerkin method that minimizes the number of flux calc
A new and efficient quadrature rule for the flux integrals arising in the space-time discontinuous Galerkin discretization of the Euler equations in a moving and deforming space-time domain is presented and analyzed. The quadrature rule is a factor three more efficient than the commonly applied quad
