Hi
First make sure that the is put in its asembly position with the right distance to the rotation axis. Then check if you have set z as axis of rotation. Choosing other axis sometimes causes problems.
Does it help?

Thank so much Hamid for your answer
In Catia i juste selecte one blade and I added the hub and shroud. When I imported the cad file .igs I don't change the rotation axis z. I success to like everything juste in expert mode and cascade configuration.

I ask you if it has any consequent in my simulation if I should this configuration. Knowen I work in radial multistage turbine.
Thank you again for your answer
