The discontinuous Galerkin method for the numerical simulation of compressible viscous flow

open access: yesEPJ Web of Conferences, 2014
In this paper we deal with numerical simulation of the compressible viscous flow. The mathematical model of flow is represented by the system of non-stationary compressible Navier-Stokes equations.

A Discontinuous Galerkin Method for Two-Dimensional Shock Wave Modeling

open access: yesModelling and Simulation in Engineering, 2011
A numerical scheme based on discontinuous Galerkin method is proposed for the two-dimensional shallow water flows. The scheme is applied to model flows with shock waves. The form of shallow water equations that can eliminate numerical imbalance between

On discontinuous Galerkin method and semiregular family of triangulations [PDF]

open access: yes, 2006
summary:Discretization of second order elliptic partial differential equations by discontinuous Galerkin method often results in numerical schemes with penalties. In this paper we analyze these penalized schemes in the context of quite general triangular

A discontinuous Galerkin method with fractal elements

open access: yesCoRR
We formulate, analyse, and implement a discontinuous Galerkin finite element method (DG-FEM) for the approximation of the solution of an elliptic boundary value problem in a domain with fractal boundary. We consider the case of the Poisson equation in the Koch snowflake domain with zero Dirichlet boundary conditions, but our methodology can be ...

The Time Discontinuous H1-Galerkin Mixed Finite Element Method for Linear Sobolev Equations

open access: yesDiscrete Dynamics in Nature and Society, 2015
We combine the H1-Galerkin mixed finite element method with the time discontinuous Galerkin method to approximate linear Sobolev equations. The advantages of these two methods are fully utilized.

Stability of ALE space-time discontinuous Galerkin method [PDF]

open access: yes, 2017
summary:We assume the heat equation in a time dependent domain, where the evolution of the domain is described by a given mapping. The problem is discretized by the discontinuous Galerkin (DG) method in space as well as in time with the aid of Arbitrary ...

The hp nonconforming mesh refinement in discontinuous Galerkin finite element method based on Zienkiewicz-Zhu error estimation

open access: yesComputer Assisted Methods in Engineering and Science, 2017
This paper deals with hp-type adaptation in the discontinuous Galerkin (DG) method. The DG method is formulated in this paper with a non-zero mesh skeleton width, which leads to a version of the method called in this paper the interface discontinuous ...
