October 7, 2014, 21:04	help with pressure gradient force	#1
socreate New Member Jas Join Date: Dec 2010 Posts: 12 Rep Power: 15	Hi, How to calculate the pressure gradient force of particles in complex and unsteady flow? The internal scheme in fluent is mainly for particles in steady flow. If I use C_P_G directly, it may cause some abnormal results. Until now, I have not found a suitable way to deal with it. Could you give me some suggestions? On the other hand, what's the intrinsic difference between C_P_G and C_P_RG except the using conditions. Thank you! Best regards, socreate
