Streamlines of Lagrangian Particles [Unsteady]
 

Hello,

Today I come to you with a question regarding Lagrangian particles: I would like to create a scene showing the trajectories of the particles. Usually this is done with the information contained in the track file, but this only works for steady sims. The simulation history file can be used to see the movement of the different particles in time, which is both useful and insightful. Yet, I am after the streamlines rather than the particles themselves.

I was thinking maybe a massless particle can be injected as kind of a seed for the streamlines, nonetheless I believe this would grant me the paths followed by the gas rather than the particles.

Anybody has experience creating the described scene? Thank you beforehand!
