I have the .stl file of a closed geometry (a simple cylinder) which I superimposed on a Cartesian hex mesh (a bigger cube) and ran snappyHexMesh. Everything works fine.

However, snappyhexmesh deletes the mesh from the region lying inside .stl file geometry.

Is there some option in snappyhexmeshdict that I can switch-off to avoid it from deleting that mesh?

I need to retain mesh on both inside and outside of the .stl surface
