Application of a Higher Order Discontinuous Galerkin

Abstract: Abstract. We discuss the issues of implementation of a higher order discontinuous Galerkin (DG) scheme for aerodynamics computations. In recent years a DG method has intensively been studied at Central Aerohydrodynamic Institute (TsAGI) where a computational code has been designed for numerical solution of the 3-D Euler and Navier-Stokes equations. Our discussion is mainly based on the results of the DG study conducted in TsAGI in collaboration with the NUMECA International. The capacity of a DG scheme to tack… Show more

“…A simple choice of the basis function in (47) may be the monomials [43] or Taylor basis [44]. However, in the case of distorted meshes, the non-orthogonality of these basis functions may yield an ill-conditioned mass matrix, resulting in degradation of accuracy and even loss of numerical stability.…”
