Please Help- Modeling unsteady velocity
 
Hi all, I want to simulate an unsteady (pulsatile) velocity in Fluent. I have approximated the waveform as sine function of the same frequency, so that it's easier to work with. The equation that I have is

Q = A + B* sin(2*pi*f*t)

I have the values of the constants and the frequency, f. How do I send this to Fluent? Do I have to write a code in C to generate this waveform? Or just define the waveform? And how do I do this? I read the Help menu, but could not figure out how to do it. Can someone help me out?

Thanks a lot.

Vidya
