EXPERIENCES OF GRID GENERATION AND STEADY/UNSTEADY VISCOUS COMPUTATIONS FOR COMPLEX GEOMETRIES

L. Tysell
FOI, Sweden

Keywords: Viscous computations, Grid generation, Complex geometries

Grid generation as well as viscous flow computations for several complex geometries have been performed. Differences in results between inviscid and viscous computations have been studied, as well as differences between steady and unsteady computations. The influence of grid resolution and choice of geometry simplification has also been studied.
