Vibrating 2D Pipe
 

Hi Guys

I am new to CFD software and need to use Fluent to simulate the effects of vibrating walls of a pipe for a Newtonian fluid on the flow (velocity & heat). I know I will need to use a UDF to simulate the vibration y(t)=A x sin(wt), however I have had very little exposure to C programming. Can someone help me with finding a UDF for this (transverse or longitudinal).

Any additional tips will also be greatly appreciated.
Thank you in advance.

Regards
Wes
