Particle Study: where do particles end up?

I'm designing a system and need to determine where particles are likely to settle. I can view the particle trajectories, but what I really need is a way to mark the spot where a given particle reaches its end condition ( ie. absorbed, opening, max time steps, etc.)   Sorry I can't show images, the product is confidential.

Does anyone know how to do this?
