All meshes were generated using gmsh and can be downloaded here: meshes.tar.bz2.

Each mesh set contains 15 meshes with logarithmically spaced characteristic lengths from coarse to fine. Plain meshes contain only the magnetic body. Shell meshes add a “space” region (free space around the body) and a “transform” region (coordinate-transformed shell mapping to infinity).
