A Simple Preconditioner for a Discontinuous Galerkin Method for the Stokes Problem
نویسندگان
چکیده
In this paper we construct Discontinuous Galerkin approximations of the Stokes problem where the velocity field is H(div,Ω)-conforming. This implies that the velocity solution is divergence-free in the whole domain. This property can be exploited to design a simple and effective preconditioner for the final linear system.

Domain Decomposition for Discontinuous Galerkin Method with Application to Stokes Flow
We report on recent results related to domain decomposition methods based on the Discontinuous Galerkin discretizations of Stokes equations. We analyze the efficiency of a block nonoverlapping Schwarz preconditioner based on the approach by Feng and Karakashian [2001]. We also prove the inf-sup stability of a substructuring method.
متن کاملGeneral element shapes within a tensor-product higher-order space-time discontinuous-Galerkin formulation
A tensor-product higher-order space-time discontinuous-Galerkin method is extended to unstructured element shapes. The use of a tensor-product formulation is key to maintaining efficiency at high polynomial orders. The discrete system of equations arising at each space-time slab is solved using a Jacobian-free Newton-Krylov scheme. An alternatingdirection-implicit (ADI) preconditioner for hexah...
متن کاملA Linear Multigrid Preconditioner for the solution of the Navier-Stokes Equations using a Discontinuous Galerkin Discretization
A Newton-Krylov method is developed for the solution of the steady compressible NavierStokes equations using a Discontinuous Galerkin (DG) discretization on unstructured meshes. An element Line-Jacobi preconditioner is presented which solves a block tridiagonal system along lines of maximum coupling in the flow. An incomplete block-LU factorization (BlockILU(0)) is also presented as a precondit...
متن کاملScalable Parallel Newton-Krylov Solvers for Discontinuous Galerkin Discretizations
We present techniques for implicit solution of discontinuous Galerkin discretizations of the Navier-Stokes equations on parallel computers. While a block-Jacobi method is simple and straight-forward to parallelize, its convergence properties are poor except for simple problems. Therefore, we consider Newton-GMRES methods preconditioned with block-incomplete LU factorizations, with optimized ele...
