blockMeshDict Geometry And snappyHexMesh
 

Hello,

Most of the information I see with respect to snappyHexMesh is the use of .stl files as geometry.

I am curious if blockMeshDict geometry creation can be used for the geometry requirements of snappyHexMesh?

Also, I will be meshing the interior of a diffuser. How can I use blockMesh to mesh interior of the diffuser if I must use an STL file?
