June 23, 2016, 17:39	UDF for Body Forces in DPM	#1
Shalabh New Member Shalabh Singh Join Date: Jun 2016 Posts: 7 Rep Power: 11	I want to write a udf for body force on particle in Discrete Phase model that includes the term 0.75Cd\|u_p-u\|rho_air(u_y-u_p_y)/(rho_p*dia_p), where u and u_p are air and particle velocities, u_y is y component of u and dia_p is particle diameter. Can anyone advise me on how to write this UDF?
