Dear Yu

Thanks for your reply.

When I use the cable dynamics and adjust the pre-tension of the anchor chain, I still get instability with negative critical damping percentage. The results of tension calculations during cable time domain calculations as well as the results of Yaw and Roll rocking of the ship don't seem to be reasonable, should I increase the critical damping in these two directions.
