April 17, 2015, 12:48	UDF for Turb. intensity	#1
mnolan93 Member Martin Nolan Join Date: Dec 2014 Posts: 33 Rep Power: 11	Hi there, I have a transient calculation with an inlet UDF for velocity and wish to specify the Turbulence intensity at the inlet and outlet, using the approximation of 0.16*Re^(-1/8). Is there a way I can define this in a UDF? Can a UDF look up the value for the Re and then calculate the TI or do I need to specify the full Re as a function of velocity in time? Thanks
