Uncompleted Mesh
 

Hi guys. I've been trying to mesh a domain with 1/3 of a turbine. The domain is cut into 3 parts, where the middle part contains the turbine blade, and the fluid will be set rotating when I import it into FLUENT.

However, somehow ICEM didn't finish the mesh of the middle slice. The mesh looks like this:

In addition to that, I found out that the periodic faces in the middle slice disappeared after meshing. Also the volume is fully mesh, just the faces aren't.
Does anyone have any idea on what happened?

Thanks in advance.
