Plotting Particle Trajectory
 

Hi guys,
I am runnning a CFD simulation using the discrete phase model. Am seeding the particle in the flow direction in a 3D pipe model. The condition in my case is the particle doesn't have initial momentum. It is being carried by the fluid flowing inside the domain. Am not able to plot the particle trajectory using Fluent. Can anyone tell me how to plot the particle trajectory? Both fluid (Continuous)phase and Particle (discrete) phase is unsteady tracking.
