Open AccessIn this work, we analyze a recently proposed stabilized finite element formulation for the approximation of the resistive magnetohydrodynamics equations. The novelty of this formulation with respect to existing ones is the ... -
Error analysis of discontinuous Galerkin methods for Stokes problem under minimal regularity
(2012)
Research report
Open AccessIn this article, we analyze several discontinuous Galerkin methods (DG) for the Stokes problem under the minimal regularity on the solution. We assume that the velocity u belongs to [H1 0 ()]d and the pressure p 2 L2 0 ... -
On the design of discontinuous Galerkin methods for elliptic problems based on hybrid formulations
(2012)
Research report
Open AccessThe objective of this paper is to present a framework for the design of discontinuous Galerkin (dG) methods for elliptic problems. The idea is to start from a hybrid formulation of the problem involving as unknowns the ... -
Convergence towards weak solutions of the Navier-Stokes equations for a finite element approximation with numerical subgrid scale modeling
