Lift coefficient
 
1 Attachment(s)
Hi, i need help with my final year project. i am simulating the transient flow condition around a sepak takraw ball, anyone has any idea why my graph of lift coefficients is showing a weird trend (as attached below)? one complete rotation of the ball takes approximately 0.06s.

Thanks in advance and any help is very much appreciated!:)Attachment 51047
