Adaptivity and a Posteriori Error Control for Bifurcation Problems III: Incompressible Fluid Flow in Open Systems with O(2) Symmetry (2011)
Journal Article

In this article we consider the a posteriori error estimation and adaptive mesh refinement of discontinuous Galerkin finite element approximations of the bifurcation problem associated with the steady incompressible Navier-Stokes equations. Particula... Read More about Adaptivity and a Posteriori Error Control for Bifurcation Problems III: Incompressible Fluid Flow in Open Systems with O(2) Symmetry.

Two-grid hp-version DGFEMs for strongly monotone second-order quasilinear elliptic PDEs (2011)
Journal Article

In this article we develop the a priori error analysis of so-called two-grid hp-version discontinuous Galerkin finite element methods for the numerical approximation of strongly monotone second-order quasilinear partial differential equations. In thi... Read More about Two-grid hp-version DGFEMs for strongly monotone second-order quasilinear elliptic PDEs.

Anisotropic hp-adaptive discontinuous Galerkin finite element methods for compressible fluid flows (2011)
Journal Article

In this article we consider the construction of general isotropic and anisotropic adaptive mesh refinement strategies, as well as hp-mesh refinement techniques, for the numerical approximation of the compressible Euler and Navier-Stokes equations. To... Read More about Anisotropic hp-adaptive discontinuous Galerkin finite element methods for compressible fluid flows.

Discontinuous Galerkin methods for problems with Dirac delta source (2011)
Journal Article

In this article we study discontinuous Galerkin finite element discretizations of linear second-order elliptic partial differential equations with Dirac delta right-hand side. In particular, assuming that the underlying computational mesh is quasi-un... Read More about Discontinuous Galerkin methods for problems with Dirac delta source.
