A little bit of context : I work as a drafter for a titanium foundry and was asked to check the design of a part (impeller). We already made the part and sent it to the client, he tested it and it failed ; some blades are destroyed upon reaching 3000 rpm.

I have no info on the fluid it is supposed to move, I just need to simulate the rotation ("empty') and see whether the blades "stay in shape" or not (sorry can't explain better in English).

Do i need to use motion study or static simulation ?

I tried both but I can't use them properly.
