Motion trajectories of an oscillating cylinder
 

Hello.

I am new to OpenFOAM and I am trying to simulate the vortex induced vibration (VIV) of a 2D cylinder. I gave 2 DoF motion in x and y directions and it seemed fine.

However, I don't know how to record the motion trajectories of the cylinder. If someone knows, please help me.
