title: Parallel Multigrid Method for Adaptive Finite Elements with Application to 3D Flow Problems creator: Richter, Thomas subject: ddc-510 subject: 510 Mathematics description: Aim of this work is the examination of numerical methods for the solution of large systems of PDE's. The equations under consideration arise from chemically reacting flows. A focal point is the analysis of a finite element discretization with stabilized finite elements of degree two. Aspects of error estimation, solution techniques and mesh adaptivity are discussed with regard to the Navier-Stokes equations. Using a well established Navier-Stokes benchmark flow the discussed methods are verified. To cope with the huge systems arising from reactive flow problems a parallel multigrid method on locally refined meshes is presented. Finally, we will perform a simulation of a methane burner in a complex three dimensional geometry. We will use a detailed reaction mechanism with 39 chemical species. date: 2005 type: Dissertation type: info:eu-repo/semantics/doctoralThesis type: NonPeerReviewed format: application/pdf identifier: https://archiv.ub.uni-heidelberg.de/volltextserverhttps://archiv.ub.uni-heidelberg.de/volltextserver/5743/1/phd_14.07.2005.pdf identifier: DOI:10.11588/heidok.00005743 identifier: urn:nbn:de:bsz:16-opus-57433 identifier: Richter, Thomas (2005) Parallel Multigrid Method for Adaptive Finite Elements with Application to 3D Flow Problems.
