HI, I'm simulating the VIV of circular cylinder. But when I reload the case and data which is saved before, there is a sudden jump in the lift coefficient Cl. I have tried a lot to solve it, But I can't find the reason. I have fall in trouble several days. I will very appreciate someone who can help me!
