A Hybridized Discontinuous Galerkin Solver for High-Speed Compressible Flow
Autor: Georg May, Koen Devesse, Ajay Rangarajan, Thierry Magin
Publikováno v: Aerospace, Vol 8, Iss 11, p 322 (2021)
We present a high-order consistent compressible flow solver, based on a hybridized discontinuous Galerkin (HDG) discretization, for applications covering subsonic to hypersonic flow. In the context of high-order discretization, this broad range of ap

Mesh Optimization for Discontinuous Galerkin Methods Using a Continuous Mesh Model
Autor: Georg May, Ajay Rangarajan, Aravind Balan
Publikováno v: AIAA Journal. 56:4060-4073
A method for anisotropic mesh adaptation and optimization for high-order discontinuous Galerkin schemes is presented. Given the total number of degrees of freedom, a metric-based method is proposed...

A continuous hp-mesh model for adaptive discontinuous Galerkin schemes
Autor: Ajay Rangarajan, Vít Dolejší, Georg May
Publikováno v: Applied Numerical Mathematics. 124:1-21
We present a continuous-mesh model for anisotropic hp-adaptation in the context of numerical methods using discontinuous piecewise polynomial approximation spaces. The present work is an extension of a previously proposed mesh-only (h-)adaptation met

Adjoint-based anisotropic hp-adaptation for discontinuous Galerkin methods using a continuous mesh model
Autor: Vít Dolejší, Ajay Rangarajan, Georg May
Publikováno v: Journal of Computational Physics. 409:109321
In this paper we propose an adjoint-based hp-adaptation method for conservation laws, and corresponding numerical schemes based on piecewise polynomial approximation spaces. The method uses a continuous mesh framework, similar to that proposed in [1]
