Particel injection using DPM
 

Dear all,
I am doing the unsteady DPM calculation and there I want to inject particle in the domain at every alternate particle time step. How to do it??

Your question is too short. Can you throw more light on what type of injection you are doing? is it combustion or what and if yes, what type of nozzle are you using? Plus did you do a steady flow simulation and got convergence before?
