Help using DPM

I am using DPM to see how long does the 1000 massless particles take to travel across my mixing tank. I am using unsteady particle tracking and track with fluid flow time step. I inject particle once at time 0, and I set max. number of steps to a very large number since I don't know how long it takes the particle to escape. However, when I start the simulation, once the at the first time step all the particles left already. That doesn't make sense, unless the particles travel the entire tank in 0.05s. I expect it should be around 300s. Can someone give me some advice?
Thanks, Eric |

I think calculate particle lag time to have an idea of time

I wonder if you have solved this problem. I run into the same problem now. Guangwei |
