Y-Velocity vs Flow time graph
 

I am working on flow over cylinder, Case is transient. I want to plot Y-Velocity vs flow Time, but the file I get from calculation activities save data only on nodes unlike the Cl file which is against flow time. How to save data for Y-Velocity against flow time? HELP

meaning?
 

What does 'save data only on nodes' mean?
Why do you think it contradicts the 'Y-velocity vs flow time' requirement?

It means that the file saved just contains node numbers in one column and y velocity in other column. I want flow time in one column instead of node numbers.
