Computation of Trailing Edge Noise with a Discontinuous Galerkin Method [PDF]

, 2010
Trailing edge noise of a semi-infinite, thin, flat plate situated in low Mach number flow is computed in two spatial dimensions. The Acoustic Perturbation Equations (APE), which are employed as governing equations, are discretized via a Discontinuous ...

Discontinuous Galerkin Forward Modeling of Wave Propagation with Split-Field Absorbing Boundary Conditions and Gradient-Based Adaptive Meshes

Mathematics
Wave propagation modeling in heterogeneous media requires numerical methods that can simultaneously handle complex geometries, artificial boundary reflections, and spatially varying resolution demands.

Application of a Discontinuous Galerkin Method to Predict Airframe Noise [PDF]

, 2009
Unstructured grids greatly ease the mesh generation process in the case of complex geometries. The Discontinuous Galerkin Method (DGM) provides a robust, high-order accurate discretization even on this type of grid.

A localized orthogonal decomposition strategy for hybrid discontinuous Galerkin methods

ESAIM: Mathematical Modelling and Numerical Analysis
We formulate and analyze a multiscale method for an elliptic problem with an oscillatory coefficient based on a skeletal (hybrid) formulation. More precisely, we employ hybrid discontinuous Galerkin approaches and combine them with the localized orthogonal decomposition methodology to obtain a coarse-scale skeletal method that effectively includes fine-

Derivation of an adjoint consistent discontinuous Galerkin discretization of the compressible Euler equations [PDF]

, 2006
Adjoint consistency - in addition to consistency - is the key requirement for discontinuous Galerkin (DG) discretizations to be of optimal order in L2 as well as measured in terms of target functionals.

Discontinuous Galerkin Computation of the Maxwell Eigenvalues on Simplicial Meshes [PDF]

, 2005
This paper is concerned with the discontinuous Galerkin approximation of the Maxwell eigenproblem. After reviewing the theory developed in [5], we present a set of numerical experiments which both validate the theory, and provide further insight ...
