frankie1988 New Member Yang Yang Join Date: Aug 2014 Posts: 1 Rep Power: 0	Hi there, I'm a college student, and I'm dealing with a particle movement issue that the DPM model is used. But I'm confused about two parameters named particle time step size and number of time steps in the particle treatment panel. How to choose the value of these two parameters? Does the particle time step size times number of time steps equal to the total time of the particle injection? Are the two parameters dependent on the start/stop time in the injection panel? Could anyone help? Thank you very much! Frankie
