Abstract
Abstract: A three dimensional flow solver is tested with external flow over a cylinder. The Reynolds number of the flow is 40. The convergence of the problem is studied with multigrid and line-Gauss-Seidel solvers for the pressure correction equation. Different ways to implement periodic boundary conditions are compared. Main result: A presentation of a three-dimensional pressure correction solver. The convergence slows down by a factor of three, if the periodic boundary conditions are ignored in the implicit phases.Description
