sh2589 New Member shk Join Date: Jul 2020 Posts: 1 Rep Power: 0	Hi, I simulate about microscale metal powder. So I want to activate particle attraction(gravity) in DEM models. I found attraction options in DEM setting and their parameters, IPEXFORCE ~ DLEXFORCE But, I can't understand each parameter mean. because there is no units and any prescription about that. please let me know about that gravity option parameters and simple examples. Thank you for your help. p
