pressure gradient modeling - please help

i am modeling a simple 2D boundary layer flow, with pressure gradients. 1. Could anyone tell me as to how I can specify a variable pressure gradient? ... 2. I have tried using udf for the pressure distribution at the wall ... is that equivalent to specify the gradient over the whole domain ...

My distribution is of the form , P = ax + b; where x is along the length of the wall...

please help, s2d.
