BladeGen: problem with periodic surfaces
 

Hi all,
after importing into Bladegen the geometry of the blade for an axial flow fan, i have exported it as a tetin file for ICEM, along with the 3D flow passage surfaces. In so doing, i have noticed that the periodic surfaces are not unique and continous: they appear divided into more sub-surfaces, while i want each periodic surface unique and continous..
Anyone can help me?

Thanks in advace.
