Pulsating flow in Fluent
 

I am currently trying to model a simple tube that is 2D-axisymetric. On the left hand side I want to specify an oscillating pressure funtion which I have as a UDF. On the opposite end of the tube I would like to specify the opposing velocity as a UDF which will be out of phase with the pressure inlet. Is there a way to do this? I have trid this which not much luck. To put it simply, I would like to be able to have the fluid be pushed through the tube at high deltaP and pulled back through at the low deltaP. Any help with this would be greatly appreciated.

Thanks
