Feature working in MachUp4 but not in MachUp5

[Neel]

Hello, 

I made a geometry in MachUp5 and tried (multiple times) to analyze its aerodynamic center, but the process kept loading and there was a timeout error (Other analyses like Forces and Moments worked fine). I then saved the .mu file and opened it in MachUp4 and again ran the analysis for the aerodynamic center, and it worked. 

I am unable to understand why the same analysis is working in MachUp4 but not in MachUp5. Can someone please let me know what is going wrong?

Thank you
