I’m using Houdini to extract physical properties from particle data.

Specifically, I need to capture particle trajectories and velocities during the simulation.

In dynamic solvers like FLIP and Pyro, how can I extract particle trajectories that are consistently aligned by unique particle IDs?

Also, since the Pyro solver isn’t based on a particle system but rather uses a velocity field, what is the recommended method to retrieve that velocity field data?

Any advice or guidance would be greatly appreciated
