Dear liladhar,
If you go to the tutorial you will see how to make a field function. Just it is enough to define parameters such as y, etc. correctly. search this phrase to see how is is the filed function for a velocity profile made:
Create Field Function for Grid Velocity

Go to the user guide and look for "field function programming reference".
