How to extract values along a line?

inf.vish · August 6, 2013, 04:46

I want to extract the values of the velocity component Ux at a particular cross section. I can plot the values along a line but how do i get openfoam to print those values for me in a file.
I need to calculate their average.

Hi,

If you are using paraFoam, you have an option "save data". It will print in a file the coordinates of the activated points (the cross section) and the different values (Ux, Uy, Uz, k, epsilon...).

Or you can use a function in the controlDict file. You have several examples in the tutorials.
