foxof90 is on a distinguished road

I am new in working with CFX software. I have created rectangular prism (3D) in which there is a single cylinder with heat generation. And my question is how to create function which describes high Pressure (101325 Pa) on the bottom of those rectangular which changes lienarly to low Pressure (0 Pa) surfece on the top of this rectangular? How to introduce those function into my model to receive pressure distribution as on the example picture?

I would be very grateful for any help.

Thanks in advance!

A CEL expression like:

Pressure = 10 [Pa/m] * z

Can be used to set a pressure boundary condition or initial condition.
