Cell Zone Size Question
 

Hello, I am working with rotating geometries, and a doubt came to my mind, I was trying to search the answer at the forums or the FUG but was not able to find anything, when you create a cell zone (in this case a rotating cell zone), how big or how small this cell zone should be? I believe that theoretically should be as small as it can, big enough to barely cover the geometry that it is moving but I have not been able to find something to support this thought. Would like to know about your opinions and ideas about this.

Thanks
