Hi all,

I am simulating a 2D flow case of circular cylinder undergoing VIV using pointDisplacement in that i am using uncoupledSixDofRigidBodyDisplacement as a displacement type and allowing the cylinder to translate only in transverse direction to flow.
I fail to understand why my cylinder oscillates for initial few secs say 10 to 20s and after that it remains stationary, what may be the reason behind this?
And when i am simulating for 2DOF i.e. translation in inline and cross flow direction, cylinder displacement is same in both the direction which i think is not possible.
Can anybody guide me on this, i am very badly stuck on this for long time.

Thanks in advance!
