[Gmsh] Transfinite volume

[ΓΙΩΡΓΟΣ ΜΑΖΑΝΑΚΗΣ]

I have just create another model, a simple octahedron (1 volume,  10 
surfaces, two of them has 8 corners) and everything works fine. Here is the 
geo file. 
So the problem it is not the number of the faces. 

Does anyone knows why in the blade case it does not work the transfinite 
algorithm (I attach the stp and script file of the blades)? 

Thanks you again for your help.
