Postprocessing the simulation output VTU file with Python

Hello, I want to explore more in my VTU file (attached) besides using Paraview, I try to write a Python script (attached) to read my VTU file, like store all the results to lists, so I can do some analysis.

I have tried both two packages from this link,

and they don’t work for me. Any one can please provide a good package?

max.vtu (2.4 MB) (443 Bytes)

I think you need to change one line in as follows?

file_name = "./Max.vtu"
