Inside and outside mesh with snappyhexmesh
 

Hey:

I am practicubg a simple case using snappyhexmesh. Basically I am trying to mesh a 2D circle from both inside and outside. The outside mesh looks perfect without any problem. The inside mesh, looks pretty ugly on the boundary. It looks like that there is some problem with snapping without inside mapping. All the parameters are the same for both cases except the locationinmesh. I am just wondering if there is something different in terms of parameter setup for the inside meshing? Thank you.
