Robust Multigrid for Cartesian Interior Penalty DG Formulations of the Poisson Equation in 3D
Joerg Stiller
We present a polynomial multigrid method for the nodal interior penalty formulation of the Poisson equation on three-dimensional Cartesian grids. Its key ingredient is a weighted o…

Robust multigrid for high-order discontinuous Galerkin methods: A fast Poisson solver suitable for high-aspect ratio Cartesian grids
Jörg Stiller
We present a polynomial multigrid method for nodal interior penalty and local discontinuous Galerkin formulations of the Poisson equation on Cartesian grids. For smoothing we propo…

Factorizing the factorization - a spectral-element solver for elliptic equations with linear operation count
Immo Huismann, Jörg Stiller, Jochen Fröhlich
High-order methods gain more and more attention in computational fluid dynamics. However, the potential advantage of these methods depends critically on the availability of efficie…
