snappyHexMesh produces a far better quality AMI interface using a cylindrical background mesh,
leading to much more robust performance, even on a relatively coarse mesh. The min/max AMI
weights remain close to 1 as the mesh moves, giving better conservation.
The rotating geometry template cases are configured with a blockMeshDict file for a cylindrical
background mesh aligned along the z-axis. The details of use are found in the README and
blockMeshDict files.
