AN UNSTRUCTURED STEADY COMPRESSIBLE NAVIER-STOKES SOLVER WITH IMPLICIT BOUNDARY CONDITION METHOD

A Parallel Compressible 3D Navier-Stokes Solver Using Unstructured Meshes

We describe in this paper a strategy for parallelising a 3D compressible Navier-Stokes solver using unstructured meshes on a class of message-passing MIMD machines. The performance results obtained on two parallel machines, the Meiko Concerto and Intel iPSC860 are presented and compared to those obtained on CRAY.

Towards a Transparent Boundary Condition for Compressible Navier–stokes Equations

A new artificial boundary condition for 2D subsonic flows governed by the compressible Navier–Stokes equations is derived. It is based on the hyperbolic part of the equations, according to the way of propagation of the characteristic waves. A reference flow as well as a convection velocity are used to properly discretize the terms corresponding to the entering waves. Numerical tests on various ...

Parallel Performance Investigations of an Unstructured Mesh Navier-Stokes Solver

A Reynolds-averaged Navier-Stokes solver based on unstructured mesh techniques for analysis of high-lift configurations is described. The method makes use of an agglomeration multigrid solver for convergence acceleration. Implicit line-smoothing is employed to relieve the stiffness associated with highly stretched meshes. A GMRES technique is also implemented to speed convergence at the expense...
