problem in pressure gradient plot

Dear friends
I use sweep mesh in my model.
I have completed transient analysis with one dimensional interpolation data with repeated cycles.

I run steady state first and then transient.

in the steady state I set pressure value 100 mm Hg at the inlet and I set 0 Pa at the outlet and then I started the transient simulation with one dimensional velocity function as inlet and pressure 0 pa at the outlet.

I checked in the CFX post I could not find any pressure contour and cannot get pressure gradient along the length of the pipe

Kindly point out my mistakes.

Can you post an image of what you do get?
