Fluent's Online help says that "You can also use the XY-plot facility to plot out the residual histories of variables, or the time histories if you have a transient problem. "

but I cannot perform this function when I wanna to plot the temperature change v.s. time marching, actually, I could not find the which parameter should be choosen in the "Plot-XY Plot" there is no an option in both Y-Axis function and X-axis function.

any suggestions would be great appreciated, Thanx a lot

I found it in tutourial 12, which gives out an example. I try it before.

if It cost yout time, I apologize for that.

Thanks

Dear Mr.Burley

Could you please tell us clearly how you were able to generate that plot? This might be useful for users like me.

for the transient problem: 1. define the point at the "surface/point..." or "surface/iso-suface..." to define the point or surface you wanna monitor (give it a easy-to-read name)

2. at "solve/monitors/surface...", open the surface monior window. according to your problem choose the number of the monitors. press the button named "define..." to enter the define suface monitor window, choose the surface of your interests, be careful to choose the X-Axis (flow-time is the popular, I think),give the file name and monitor name. then press OK to go back surface monior window, here you need to check /uncheck those boxes if you wanna see the fligure during calculation, they are easy to understand. remember to give a easy-to-read name, press OK

3. go through you calculation 4. you can draw the .out file via "plot/file..."

good luck

Burley
