UDF for pulsing flow.

Would anyone have a udf that allows me to place a pulsatile flow at the exit from my pump, which is also elliptical in profile? I am modelling a single balded pump, so there is a large pressure pulse in each revolution. I have successfully implemented a udf to allow for this pulsing effect, but I would like ot make it so that the velocity profile is parabolic at the exit rahter than flat as is the case with the udf. So, how do I implement a parabolic profile on to a pulsing flow? Needless to say, the problem is been run unsteady.
