Multigrid Solver Algorithms for DG Methods and Applications to Aerodynamic Flowsto aerodynamic flows. In particular, we present an application of multigrid algorithms to a higher order DG discretization of the Reynolds-averaged Navier-Stokes (RANS) equations in combination with the Spalart-Allmaras as well as the Wilcox-. turbulence model. Based on either lower order discretiza

Time Integration in the Discontinuous Galerkin Code MIGALE - Unsteady Problemsing high-order implicit time integration schemes. The approaches considered during the IDIHOM project were the Implicit Large Eddy Simulation (ILES), where no explicit subgrid-scale (SGS) model is included and the DG discretization itself acts like a SGS model, and two hybrid approaches between Reyn

A High-Order Finite-Volume Method with Block-Structured Local Grid Refinementred grid resolution in the vortex region, block wise local grid refinement is employed. A new topology-based block refinement algorithm allows the efficient generation of such block-wise refined meshes. The high-order finite-volume method is extended with high-order interpolation to deal with the pa

Aghora: A High-Order DG Solver for Turbulent Flow Simulationsnolds averaged Navier-Stokes equations coupled with turbulence transport equations, variational multi-scale formulation of large-eddy simulation, and direct numerical simulation. The space discretization is based on a high-order discontinuous Galerkin method with representation of curved boundaries.

Implementation of High-Order Discontinuous Galerkin Method for Solution of Practical Tasks in Extern. = 2, 3 with 1st order implicit smoother is proposed. Modifications, which were introduced in the method to achieve stability and fast convergence, are described. The method is enhanced by the use of improved Gauss quadrature rules and by the use of improved Gauss quadrature rules and of . − . mult

High-Order Residual Distribution and Error Estimation for Steady and Unsteady Compressible Flown the use of spatially varying distribution matrices. Following this, the application to adjoint-based error estimation for steady compressible flow is presented. Finally the resolution of acoustic wave propagation by a space-time residual distribution is discussed. The accuracy of the methodology i
