How to handle this error on Simlab when simulating CFD?

Hi expert,
Currently I am trying to simulate a simple CFD problem as follows: air flow through the propeller. I have set up as the model below and the software gives error like the picture.
So where did I go wrong and how do I fix it?
Thanks everyone.
