Here is a little script that shows you how to read and write dataset in
ParaView using a simple for loop.
Hope this helps.

Thanks for the tip. I actually already used tracing in order to find the
command:
Probelocation.ProbeType.Center = [10.0,20.0,30.0]
But the problem is that I don't know how to access to the data (rho, vx,
vy...) at that location in the python script
And since tracing does not capture "Save data", I don't even know how to
write the data in a file
Cheers,

Hi McFly,
The Python Tracing facility in ParaView is perfect for this kind of
task. It records a trace of your actions in the ParaView GUI to a Python
script that you can modify a bit to process a bunch of files. To turn on
tracing, choose the Tools -> Start Trace menu item.
More info on tracing is available in the ParaView User Guide [1] under
section 1.6.2.
Best regards,
Cory

Hi everybody,
I am a new Paraview user. I am trying to extract points from a bunch
of vtu files. It is pretty easily done with "probe location". But
since I have a lot of files, I would like to automatize the process
(with a macro or a python script).
Could someone maybe show me how it's done?
My best guess is that I should have the following in a python script:
Probelocation.ProbeType.Center = [10.0,20.0,30.0]
assuming I want to probe at x=10, y=20, z=30. But then, I don't
really know how to retrieve the variables values at that location.
Thanks a lot,
Mc Fly
