An hp-version discontinuous Galerkin method for integro-differential equations of parabolic type [PDF]

open access: yes, 2011
We study the numerical solution of a class of parabolic integro-differential equations with weakly singular kernels. We use an $hp$-version discontinuous Galerkin (DG) method for the discretization in time.

A two-level enriched finite element method for a mixed problem [PDF]

open access: yes, 2011
The simplest pair of spaces is made inf-sup stable for the mixed form of the Darcy equation. The key ingredient is to enhance the finite element spaces inside a Petrov-Galerkin framework with functions satisfying element-wise local Darcy problems with ...

An optimal order interior penalty discontinuous Galerkin discretization of the compressible Navier-Stokes equations [PDF]

open access: yes, 2008
In this article we propose a new symmetric version of the interior penalty discontinuous Galerkin finite element method for the numerical approximation of the compressible Navier-Stokes equations.

Compact and stable discontinuous Galerkin methods for convection-diffusion problems [PDF]

open access: yes, 2012
We present a new scheme, the compact discontinuous Galerkin 2 (CDG2) method, for solving nonlinear convection-diffusion problems together with a detailed comparison to other well-accepted DG methods.

Discontinuous Galerkin finite element approximation of nonlinear second-order elliptic and hyperbolic systems [PDF]

open access: yes, 2006
We develop the convergence analysis of discontinuous Galerkin finite element approximations to second-order quasilinear elliptic and hyperbolic systems of partial differential equations of the form, respectively, $-\sum_{\alpha=1}^d \partial_{x_\alpha ...

Consistent local projection stabilized finite element methods [PDF]

open access: yes, 2010
This work establishes a formal derivation of local projection stabilized methods as a result of an enriched Petrov-Galerkin strategy for the Stokes problem.

Energy consistent discontinuous Galerkin methods for a quasi-incompressible diffuse two phase flow model [PDF]

open access: yes, 2013
We design consistent discontinuous Galerkin finite element schemes for the approximation of a quasi-incompressible two phase flow model of Allen--Cahn/Cahn--Hilliard/Navier--Stokes--Korteweg type which allows for phase transitions.

Analysis of the discontinuous Galerkin method for elliptic problems on surfaces [PDF]

open access: yes, 2013
We extend the discontinuous Galerkin framework to a linear second-order elliptic problem on a compact smooth connected and oriented surface in ℝ3. An interior penalty (IP) method is introduced on a discrete surface and we derive a priori error estimates ...

Interior penalty discontinuous galerkin methods for electromagnetic and acoustic wave equations [PDF]

open access: yes, 2006
Introduction: In this thesis we present and analyze the numerical approximation of the second order electromagnetic and acoustic wave equation by the interior penalty (IP) discontinuous Galerkin (DG) finite element method (FEM).
