Hi, I have a blade divided into two parts using Overset mesh. The first half of the blade is rotating about 0 0 and the second half relative to first half so 0 0. Now i want to rotate the second half about its own axis using 1 DOF spring connection with certain K. Everything works well. When I am activating the 6DOF solver and putting certain values in the , it asks for center of rotation in case of rotational spring 1DOF. In my case, it would be the blade's second half pitching point. But, there is no way to put the daming for the spring, how can i use a damper in this case?

Additional info: Blade second half is an overset zone and the first half main zone. So i want this whole overset zone to rotate as per the forces acing on the wall and respect the spring connection.
