UDF for periodic boundary condition
 

Hi guys,

I am very new in Using UDF. I need some urgent help.

My case is flow along a pipe . Instead of taking a long pipe , I want to simulate a slice , say 50mm long , dia=50mm. Velocity inlet and outflow at outlet. Z is the axis of pipe. After every iteration , the cell centred values ( like velocity , turbulence quantities ) from outlet will be read and stored using UDMI and updated in inlet.


If anybody write me a sample UDF ( lets only for velocity) for this , I will be really obliged.


Regards
Angie
