Bubble stabilization of discontinuous Galerkin methods [PDF]

open access: possibleComputer Methods in Applied Mechanics and Engineering, 2009
We analyze the stabilizing effect of the introduction of suitable bubble functions in DG formulations for linear second order elliptic problems, working, for the sake of simplicity, on Laplace operator. In particular we find that the addition of a single b ubble per element can stabilize the non- symmetric formulation of Baumann-Oden Most commonly used

An Immersed Discontinuous Galerkin Method for Acoustic Wave Propagation in Inhomogeneous Media

SIAM Journal on Scientific Computing, 2019
We present an immersed discontinuous Galerkin finite element method on Cartesian meshes for two dimensional acoustic wave propagation problems in inhomogeneous media where elements are allowed to b...

Discontinuous Galerkin Methods [PDF]

open access: possible, 2012
In this final chapter we present the discontinuous Galerkin (dG) method. This method is based on finite element spaces that consist of discontinuous piecewise polynomials defined on a partition of the computational domain. Such methods are very flexible, for example, since they allow construction of more general methods and since they allow for simple ...
