Got it, I just ran the same with fixed condition (as shown in vedio). However, the results still dont match the analytical results (attached below)  

Cyclic symmetry: 

 

Boundary conditions:  

Equivalent stress:  

Normal stress in y (centrifugal stress): 

 

I tried an ansys tutorial as well, Chapter 14: Static and Modal Analysis of a Compressor Model with 4 Axial Stages 

The stress values here also do not match with analytical. Is the method of viewing the results correct? Please suggest if there is any reference for centrifugal stress in turbomachinary components that I can go through. Thank you.
