The problem about the terminate of particle trajectory
 

Hi world,
When I calculate the trajectory of particles using DPM model, many particles remain in domain after long time calculating. I want to terminate the particle trajectories after some time, for example 2s, how can I achieve it through UDF?
I hope your reply, thanks in advance.

I did not understand well your question, but if you want all particles to come out of the domain i think you would increase the number of steps.
