Hello everyone,

I'm new with fluent and I am trying to draw the graph of skin friction coefficient variation with the changing x distance for a flow through a cylindrical pipe. I have successively drawn the temperature and pressure charts but when I try drawing the Cf chart, I simply get nothing but the x and y axis. Here the link of my exercise (please scroll down until the skin friction coefficient part), and ss of my result is attached:

Thanks for you help.

Did you calculate the skin friction coefficient in Fluent? If not Go to File>Data File Quantities and select Skin friction Coefficient. Click on Calculate. After completion of the calculation check the results by plotting the Cf chart.

Thank you. But the problem is solved. I have defined the coordinates of pipe wall and centerline as wrong. Sorry about that.
