  Hi, I am trying to create UDF for my simulation with an initial velocity profile of 65mm at the inlet and velocity of 40m/s. I tried using the fo4mula below to write a UDF for my rectangular domain but I can't seem to manipulate the initial velocity at the beginning of the inlet to a have velocity profile of 65mm. Below is a copy of my UDF, Domain description, and the exprimental description of what I am trying to achieve at the beginning of my inlet
  
  NOTE: I am able to achieve a desired 65mm velocity profile at the desired location (of 4m from the inlet) but not at the inlet
  
  Formula U=ref(z/Zref)gamma
  
  Uref=40m/s
  
  Z=z(Height of Domain 1,32m)
  
  Zref=65mm
