Local Discontinuous Galerkin Methods for the Stokes System [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2002
A discontinuous Galerkin method for the Stokes problem is introduced and analysed. A priori error estimates for velocity and pressure are derived, which are shown to be optimal, if proper polynomial approximations and stabilization parameters are used.

Local Discontinuous Galerkin Methods for the abcd Nonlinear Boussinesq System [PDF]

open access: yesCommunications on Applied Mathematics and Computation, 2021
Boussinesq type equations have been widely studied to model the surface water wave. In this paper, we consider the abcd Boussinesq system which is a family of Boussinesq type equations including many well-known models such as the classical Boussinesq system, BBM-BBM system, Bona-Smith system etc.

Error Estimates for Local Discontinuous Galerkin Methods for Linear Fourth-order Equations

open access: yesJournal of Harbin University of Science and Technology, 2021
This paper studies the stability and error estimates of the local discontinuous Galerkin method for fourth-order linear partial differential equations based on upwind-biased fluxes. Consider using the semi-discrete form of numerical format in the spatial

The local discontinuous Galerkin method for the Oseen equations [PDF]

open access: yesMathematics of Computation, 2003
We introduce and analyze the local discontinuous Galerkin method for the Oseen equations of incompressible fluid flow. For a class of shape-regular meshes with hanging nodes, we derive optimal a priori estimates for the errors in the velocity and the pressure in

On the Local Discontinuous Galerkin Method for Linear Elasticity [PDF]

open access: yesMathematical Problems in Engineering, 2010
Following Castillo et al. (2000) and Cockburn (2003), a general framework of constructing discontinuous Galerkin (DG) methods is developed for solving the linear elasticity problem. The numerical traces are determined in view of a discrete stability identity, leading to a class of stable DG methods. A particular method, called the LDG method for linear

A local discontinuous Galerkin method for the Burgers–Poisson equation [PDF]

open access: yesNumerische Mathematik, 2014
The authors design, analyze and test a local discontinuous Galerkin method for solving the Burgers-Poisson equation. The proposed numerical method is high order accurate and preserves both momentum and energy invariants. The \(L^2\)-stability of the scheme for general solutions is a consequence of the energy preserving property.
