We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Thank you for your response. So I am simulating radially loaded Deep Groove Ball Bearing with 9 balls. I have modeled only 1 ball = 40° out of 360°. So the code would change to:

cpcyc,all,,1,,40 

allsel,all

1. Am I right?

2. Since this is radially loaded ball bearing, the load on each ball/sector (40°) would NOT be same. Then should I still proceed with Cyclic Symmetry or Normal Symmetry is preffered?

3. I will continue this modeling for FSI (MEch-Fluent). So the SAME symmetry needs to be modeled there for oil flow in Ansys Fluent?

 

 4. Is it not possible to elminate the symmetry option and just apply some constraints on both the sides so I am only focusing on 40° model making my simulation analysis easier.

Thank you !

 

UPDATE: Transient structrural does not work with Cylic Symmetry even if we use the command snippet as u mentioned.
