I need to get trajectories for fluid particles in my tests. Is there any way I could get particle trajectories from Dualsphysics ? It seems a feature will be added in the next version called tracerparts but any suggestions for me I could use to get particle trajectories for now? I am using version 5. I have seen in some workshop presentations a part called TracerVTK but I could not find it in the source package of version 5.
