Bulky edges using snappyhexmesh
 

Hi,
I'm having troubles getting the edges properly meshed using snappyHexMesh. The geometry is modelled using blender, where SnappyHexMeshDict and .stl files are generated through swiftsnap-addon in blender. As seen from the attached images the edges wont snap properly and the surface is bulky near the edges. I have tried alternative settings for the snapcontrol entries and disabled some of the MeshQualityControl as the minTetQuality (set to 0.5), but then the checkMesh fails. I would be really happy if anyone could help or leave some comments on what might be wrong. I have attached files for running snappyHexMesh.

Thanks,
