Fourier analysis for discontinuous Galerkin and related methods
We provide a framework for the analysis of a large class of discontinuous methods for second-order elliptic problems.
○ how do we choose the flux it must be consistent (tend to the real flux) and control the dissipation to insure the stability.
The discontinuous galerkin (dg) method we discuss in this paper is a class of nite element methods, using a completely discontinuous piecewise polynomial space for the numerical solution and the test functions. One main advantage of the dg method was the exibility a orded by local approximation spaces combined with the suitable design of numerical.
We derive explicit expressions for the eigenvalues (spectrum) of the discontinuous galerkin spatial discretization applied to the linear advection equation.
We have evaluated a numerical dispersion-dissipation analysis for two discontinuous galerkin methods (dgms) — the flux-based dgm (fdgm) and the interior.
27 oct 2020 pdf we provide a common framework for the understanding, comparison, and analysis of several discontinuous galerkin methods that have.
A central discontinuous galerkin method for hamilton-jacobi equations by fengyan li, sergey yakovlev - j sci comput 2010 in this paper, a central discontinuous galerkin method is proposed to solve for the viscosity solutions of hamilton-jacobi equations.
And analysis of several discontinuous galerkin methods that have been proposed for the numerical treatment of elliptic problems. This class includes the recently introduced methods of bassi and rebay (together with the variants proposed by brezzi, manzini, marini, pietra and russo), the local discontinuous galerkin meth-.
In this paper we present an analysis of three different formulations of the discontinuous galerkin method for diffusion equations.
Keywords: discontinuous galerkin methods, finite element methods. Ams (1991): finite element method for diffusion problems: 1-d analysis.
In applied mathematics, discontinuous galerkin methods (dg methods) form a class of numerical methods for solving differential equations. They combine features of the finite element and the finite volume framework and have been successfully applied to hyperbolic, elliptic, parabolic and mixed form problems arising from a wide range of applications.
We analyze a local discontinuous galerkin method for fourth-order time-dependent problems.
In turn an extension of the runge-kutta discontinuous galerkin (rkdg) method developed by cockburn and shu [19], [22], [23], [24], [26] for nonlinear hyperbolic systems. The ldg method is one of several discontinuous galerkin methods which are being vigorously studied, especially as applied to convection-diffusion problems,.
The subject of the book is the mathematical theory of the discontinuous galerkin method (dgm), which is a relatively new technique for the numerical solution of partial differential equations. The book is concerned with the dgm developed for elliptic and parabolic equations and its applications to the numerical simulation of compressible flow.
Hesthaven 2007-12-18 this book offers an introduction to the key ideas, basic analysis, and efficient implementation of discontinuous galerkin finite element.
Section we will discuss the algorithm formulation, stability analysis, and error estimates for the discontinuous galerkin method solving hyperbolic conservation.
The projects focus on the design, analysis, and implementation of discontinuous galerkin (dg) finite element methods for approximating both linear and nonlinear partial differential equations. Dg methods are a generalization of finite element methods in that they allow for fully discontinuous piecewise polynomial basis functions.
Discontinuous galerkin methods were first proposed and analyzed in the early 1970s as a technique to numerically solve partial differential equations.
