January 29, 2015, 05:44	Computation of friction velocity in a UDF	#1
azzurroblake New Member Join Date: Nov 2014 Posts: 3 Rep Power: 12	Hi guys, do you know how to compute an area-averaged value of the friction velocity (sqrt(tau_wall/rho)) in a UDF? I can easily do it in the GUI, but I need to use that value in a UDF. Thank you in advance for your support.
