[Paraview] Selecting points from mesh in PARAVIEW using pvpython

[jrojasca at ens-paris-saclay.fr]

Hello,

I am working to make a selection of points from a unstructured grid  
(associated to a .xmf file) in Paraview  to carry out a FFT of them  
later on. Doing this by using the GUI of Paraview is fairly   
straightforward since there are several options to select these  
points. However, I need to this by coding it from the python shell  
option.

I have already looked several books, presentations and help online  
without finding an example or a specific explanation about how to code  
the selection of  points by using python.

I would really appreciate your help regarding this subject,

Regards,

Juan
