hi me again. i read about the sample utility and decided that it is a much cleaner way to plot graphs than probe. my problem is that after i finished a calculation with FoamX and i puch the execute button for sample (configuration: uniform, along a line) it is initializing the mesh and writing something for every iterationstep, but than if i take a look in the dictionary on my hd (sample) and if i go to any iterationstep, there is absolutely no data written there? someone can help?

All data extracted using the s
 

All data extracted using the sample utility gets written to a new directory called samples inside your case.

jup thats what i thought....in that samples directory there are all the iterations steps in new directories. but these directories are empty there is no data

That's odd. Do one thing. Use the default caviy case with icoFoam and extract the velocities along a line through the center of the cavity. See if that works first.

Hallo Robert,

1. Which version of OF do you use? I had also some problems with sampling in OF-1.3? Try to change the interpolation in the sampleDict.

2. Make sure your sample line (coordinates of first and last point) is within your domain!

thx a lot, i use version 1.4..
 

thx a lot, i use version 1.4......well my first and last point are exactly on my left and right boundary. is that allowed? anyway i am going to try it tomorrow at the pc at work. what do you mean by changing the interpolation? i used uniform and 100 points in between

I faced the same problem a while ago[1]. The suggestion was to move to the cloud option as opposed to the line option. Check the thread below for more information.
