Bubble Stabilized Discontinuous Galerkin Method for Stokes’ Problem
نویسنده
چکیده
We propose a low order discontinuous Galerkin method for incompressible flows. Stability of the discretization of the Laplace operator is obtained by enriching the space element wise with a non-conforming quadratic bubble. This enriched space allows for a wider range of pressure spaces. We prove optimal convergence estimates and local conservation of both mass and linear momentum independent of numerical parameters.

A stabilized finite element method using a discontinuous level set approach for the computation of bubble dynamics
A novel numerical method for solving three-dimensional two phase flow problems is presented. This method combines a quadrature free discontinuous Galerkin method for the level set equation with a pressure stabilized finite element method for the Navier Stokes equations. The main challenge in the computation of such flows is the accurate evaluation of surface tension forces. This involves the co...
متن کاملOn the stability of bubble functions and a stabilized mixed finite element formulation for the Stokes problem
In this paper we investigate the relationship between stabilized and enriched finite element formulations for the Stokes problem. We also present a new stabilized mixed formulation for which the stability parameter is derived purely by the method of weighted residuals. This new formulation allows equal order interpolation for the velocity and pressure fields. Finally, we show by counterexample ...
متن کاملError Analysis of Discontinuous Galerkin Methods for Stokes Problem under Minimal Regularity
In 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 [H 0 (Ω)] d and the pressure p ∈ L0(Ω). First, we analyze standard DG methods assuming that the right hand side f belongs to [H−1(Ω) ∩ L(Ω)]. A DG method that is well defined for f belonging to [H−1(Ω)]d is then inv...
متن کاملBubble stabilized discontinuous Galerkin method for parabolic and elliptic problems
In this paper we give an analysis of a bubble stabilized discontinuous Galerkin method (BSDG) for elliptic and parabolic problems. The method consists of stabilizing the numerical scheme by enriching the discontinuous finite element space elementwise by quadratic non-conforming bubbles. This approach leads to optimal convergence in the space and time discretization parameters. Moreover the dive...
متن کاملLocal and pointwise error estimates of the local discontinuous Galerkin method applied to the Stokes problem
We prove local and pointwise error estimates for the local discontinuous Galerkin method applied to the Stokes problem in two and three dimensions. By using techniques originally developed by A. Schatz [Math. Comp., 67 (1998), 877-899] to prove pointwise estimates for the Laplace equation, we prove optimal weighted pointwise estimates for both the velocity and the pressure for domains with smoo...
