Taz-CFD New Member Taz Hussain Join Date: Feb 2016 Posts: 8 Rep Power: 10	Hi guys, really stuck so any help/guidance would be greatly appreciated. I'm simulating turbulent flow within a 3D pipe and am looking to implement a UDF to create fully a turbulent flow profile at the inlet. My inlet is parallel to the x axis/perpendicular to z and the symmetry condition in y throughout the whole pipe. Ive found many 2D UDF guides but not any 3D turbulent flow UDF's. I am also struggling to work out the parabolic equation. I also need my average velocity - do I just take the from FLUENT using the surface integrals? If anyone can guide me on where to start or point to any existing codes, I would really appreciate it! Regards, Taz
