Background Mesh generation for SnappyHex
 

Hi!

I am new to OpenFoam and I've been struggling for a couple of days now to understand how a BG mesh is generated for SnappyHex meshing. I am working on a 3D model, and as far as I understand my BG mesh has to be a box which contains the whole 3D geometry. However, part of my geometry is just not converted, although if I look at it in my external mesher (I use CFX mesher), the geometry is fully included in the box which I use to generate BG mesh. Any ideas where am I going wrong? Thanks in advance.
