In the following chapters a state-of-the-art Multigrid Solver is investigated and possible improvements are discussed. This solver is designed to solve the Navier-Stokes equation in two steps. In this solver, an intermediate velocity is computed via the Chorins projection using pressure values from a previous step. Secondly a pressure correction is made by using a pressure Poisson equation. The improved solver is tested against the original version in several scenarios that demonstrate an increase of speed up to a factor of 65. The final chapter provides the reader with some ideas on how the performance of a Multigrid Solver could be further improved.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786202214780\"\u003e\u003ch3\u003eApplication on HPC Fluid Flow Simulations\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9786202214780","offer_id":39465136160861,"sku":"9786202214780","price":43.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/e5229cb2-846e-45d0-8d08-d93e65cf223a.jpg?v=1758089358","url":"https:\/\/shop.autorenwelt.de\/products\/optimisation-of-a-parallel-multigrid-solver-for-hpc-simulations-application-on-hpc-fluid-flow-simulations-von-thomas-jungblut","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
