  You want to plot with a different scale or find the volume with a speed below a certain value?

    If you right-click surfaces -> New, on the bottom there is Expression Volume. Here you can define your limit, such as VelocityMagnitude<2 [m/s] . Then you can make a Report of this volume.

    Yeah, you Fluent guys sometimes put in some helpful things. I used to have to go over to CFD Post to do it there.

    Please see attached. Which version are you using? If it is an older version it may not be available. In that case the approach I would use then is to go over to CFD-Post. Do you have access to that?
