Velocity "ripples" at AMI
I'm getting what looks like ripples at the AMI in my 2D mesh after using snappyHexMesh. The meshing dicts are based on those by another forum member Boloar. When I mesh that case, there is no rippling, but when I insert my own geometry (including a smaller cylinder as the AMI surface), I get these ripples. I have meshed with many different refinement levels, iteration numbers, etc., but still the same. Anyone have an idea on what parameter would cause these ripples?
