I am using the DPM model to inject the particles. I selected “group type” and “no. of stream= 20.” and my study is “transient”. A micro-shock tube is used, and the driver section is patched with a high-pressure gas and the driven section is patched with a gas at atmospheric pressure. 

 

I am facing a problem: “Whenever I run the simulation at the same condition, in each simulation, the particle velocity at the nozzle exit is different, and the particle is reaching at a different time at the nozzle exit.” 

Also, in each simulation, the message in the console is " the reverse flow on 168 faces of pressure outlet-12." appearing after every time step.

Why is it so?
