Abstract

The development and validation of a parallel unstructured tetrahedral non-nested multigrid method for simulation of unsteady 3D incompressible viscous flow is presented. The Navier-Stokes solver is based on the artificial compressibility method (ACM) and a higher-order characteristics-based finite-volume scheme on unstructured multigrid. Unsteady flow is calculated with an implicit dual time stepping scheme. The multigrid domain decomposition approach (MG-DD) is adopted for the multigrid parallelization. The Message-Passing Interface (MPI) Library is used for communication of data and loop arrays are decomposed using the OpenMP standard. The parallel codes using single grid and multigrid are used to simulate steady and unsteady incompressible viscous flows for a 3D Hd-driven cavity flow for validation and performance evaluation purposes. The parallel results obtained agree well with those of serial solvers and with numerical solutions obtained by other researchers, as well as experimental measurements.
