Default harmonic wave

I like to thank every one for answering questions on this site. It is a real source of help for me.

I have another simple question as I said before I am very new to CFX

i AM MODELING A pipe with same diameter on the inlet and outlet, I am trying to run a transient analysis.

on the inlet I want to apply a sin(t) and observe the wave motion as it propgated in the pipe.

I think the way to go is to apply it through expresions and functions, I have done that but how can I relate this created expression (sint) to my inlet boundary conditions

Am I doing the wright thing, if there is a btter way pls let me know

Have a look at tutorial 3 in the CFX examples. It uses a CEL expression to control the fluid viscosity but the same concept can be used to control boundary conditions as well.
