hami9293 New Member Terry Tensinsky Join Date: Feb 2010 Posts: 14 Rep Power: 16	Hi, I want to simulate a flow in a pipe. my boundary condition, is velocity at the internal of the pipe. velocity has two componants: a) an unsteady axial flow b) a steady circumferential flow. I think it requires a UDF. I have written the UDF for the first part. it is easy. But I don't know how can I do the second part. Is there any one can help me ?
