Is it possible in CFX?

Hi Guys

I wanna have pressure inlet as my inlet BC but make it function of time. Is it possible to do that in CFX? If yes, how do i go about it.

Thanks

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

Nope i dont have an equation. I dont quite understand what you meant by table of values. Infact i was looking for an equation. Do you have one? Thank you

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?

I was hoping thats what CFX is gone tell me if i can write an equation for pressure inlet.

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

I get you guys now. I was a bit confused with whole process. My colleague is gone conduct experiment, then i will ask you guys for help. Thank you

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.
