UDF of pressure wave....not travelling
 
3 Attachment(s)
Hello all,
I am trying to validate a simple pipe flow problem in ANSYS (FSI). the respective properties and boundary conditions are applied as per the paper (attached with the thread). I have run the solution, but the results are not as expected, the pressure wave is not travelling through the pipe.
I am using system coupling(transient structural+ Fluent).
Please help me.....
