Use this expression variable. After that click 'Insert chart'. here use the same variable defined for velocity on y axis and use time variable of x axis. Here advanatge is that you dont need to 'set monitors', save them and again use the saved monitor file in fluent to plot. I hope it would be helpful.

Hello,
I am facing a similar problem in plotting the velocity vs time graph. Can you please elaborate on this step?

Hi in CFD post under the graph section, there is an option to plot transient data with x as time/frequency....

For that you have to create a points in CFD post and select the point as a region to plot the results. It takes a while to calculate the variables. Good luck with your post processing

I would like to set up a monitor plot for the velocity at a particular point. I tried doing it through surface monitor but I am not sure about the report type that is to be selected. How do I do it?
