After generating a mesh with blockMesh, I utilize snappyHexMesh to refine the grid in two regions, one region comprises the turbulent boundary layer, and the other is next to the first region. However, when I run the simulation and get my results, they are totally screwed up. It seems snappyHexMesh is doing something funny to the grid. I must say though, the initial mesh does not have an aspect ratio even close to 1. I am using LES turbulent boundary layer grid criteria (wall units). So is snappyHexMesh only good for aspect ratios close to 1? Deji
