NEED HELP TO create UDF to define a boundary condition automatically
 
i must create a UDF to define a velocity inlet at the face of my box which is normal to "y axis" and which is the closest and the furthest will be a pressure outlet. and the other faces will be walls.
need a udf because i have many geometries and because the box has been separate in random faces.

How are you setting up your case? Not sure if a udf macro exist for doing what you want. But you could use a journal file to help you automatically setup your entire Fluent case including defining your bcs. Jimmy

But like i said my boxes which enclosure my geometries are separate in 6 random faces. so i can't use a journal file
