SHM Problems with snapping and layers

Dear Foamers,

I am struggling to get continuous layers on the mesh in the attached file. (The only geometry is 'fixed_surroundings.stl')

I am using OF 3.01

As you can see from a horizontal and vertical section the layers are not continuous. I have also noticed that if I keep my refinements for features and surfaces below 6 then SHM does not snap to the top-left vertical edge.

The series of commands that I run is the following:

Code:

foamCleanPolyMesh
blockMesh
surfaceFeatureExtract
decomposePar
mpirun -n 2 snappyHexMesh -parallel
reconstructParMesh
foamToVTK

I have read several posts and made lots of tests, but cannot understand whether I am doing something wrong.

Any idea?
