hedi-72 New Member Hedieh Join Date: Jan 2016 Posts: 2 Rep Power: 0	Hi everybody, I'm working on my school project with fluent and I want to apply some boundary conditions on a specific length of boundary and the length is proportional to the time. Is it possible to define these feathers on each boundary condition with UDF? If not, what should I do? I'm not experienced much in fluent specially UDFs and i'll be appreciated if you could help me with this problem. Thanks for your help,
