Yes. Enter an expression for the pressure which is a function of 't'. Do you have an equation or a table of values?

If you don't have a table of values or an equation, how do you know how your pressure is going to vary with time?

Sir Alpha, you must to choose an equation for your problem! Or, u can add experimental data, eg, 2,000 points from your experiments!

Asking CFX to write the equation is like asking Excel to create your spreadsheet. If you have an equation or experimental data, you can use it. It can't automagically come up with one.
