Tip Clearance

Liam

I am having a few problems generating a grid with tip clearance in CFX Turbogrid. Whenever I export a set of Turbogrid input files from BladeGen and import them into Turbogrid it seems as though Turbogrid has trouble detailing the blade tip at the shroud. I have tried various blade geometries and in some cases it seems to add an extra piece of material to the leading edge at the shroud and in other cases it seems to remove a piece of material. I have attached a word file containing a picture of an example were it seems to have removed some material. I am unable to generate a grid with tip clearance without it containing a very low skew angle.

Any help would be greatly appreciated.

Kind Regards
