The ball is moving, so there is no need to set a velocity on the wall in Fluent.

Please understand the purpose of system coupling is to transfer displacement, so if the ball is moving in mechanical and there is a system coupling region scoped to it, it will transfer that movement to Fluent.

As for cyclic symmetry indeed, it is not compatible with SyC. You need to define it via a command snippet CPCYC instead of the cyclic symmetry object. Please check the help for usage.
