baffle in flow route
 

How can I make a volume mesh for an empty box which contains a thin baffle? This baffle was set at the center of this empty box. I have assign each parts e.g. pts, curves and surfaces including the baffle for my model and given them max mesh size. When meshing complete and transferring into CFX, I can not see the "baffle" part under the tree of assembly. But when I use scan-plane in ICEMCFD, I can be sure that nodes and vertices have been located on the baffle.
