I try to create 3D geometry with 3 elements: pipe (inlet) + box + pipe (outlet). Mesh is attached here.
blockMeshDict
As i understand (reading Manual & Forum), to support continuity of fluid domain it is need to use mergePatchPairs for outlet of the 1-st pipe and inlet of the 2-nd pipe. But blockMesh writes it:

Could abybody explain whats wrong ? Need help !
