SnappyHexMesh without refinement
 

Dear all,

For some purpose, I need to use snappyHexMesh without refinement, just to remove cells which are overlapped with interior regions of 3D geometry (stl etc).

If you know how to set the snappyHexMeshDict, or treat different manner,
I would appreciate it if you could help me.

Kind regards

I could solve this problem by myself, thank you.
