ParaView can write the Python script for you using the Python Tracing feature, which records actions in the ParaView desktop application as Python code. The ParaView Guide has examples of Python scripting throughout. Get started writing ParaView Python scripts Programmable data sources and filters provide low-level access to data and enable you to perform custom data filtering operations not already available in ParaView. In addition to scripting ParaView visualization pipelines, ParaView provides several ways to enhance its capabilities. You can leverage scripting in ParaView to quickly develop more tailored solutions through the Web or as standalone applications.

Python scripts for ParaView form a basic building block of custom web-enabled visualization applications using platforms like ParaViewWeb and trame. Python scripts for ParaView form a basic building block of custom web-enabled visualization applications using platforms like ParaViewWeb and trame. If you can script it, you can visualize it on the web! They can also be invoked as part of in situ analysis while a simulation is running using Catalyst. ParaView also supports scripting and batch processing using Python. Scripts even work in client/server mode and on servers running on thousands of processors. This is especially useful in batch processing so you can extract meaningful information from large simulations, either in situ or post-processing. The writer will update the time steps itself and save the results (you don't need anymore the for loop). Scripting lets you easily streamline repetitive jobs, handle intensive tasks without interaction, and create dedicated solutions for their needs. I didn't try to see what happens with your script, but if you don't need to change anything between the time steps you can just set the pipeline once, and then add writer.WriteAllTimeSteps 1. ParaView’s Python scripting layer is useful when the interactive exploration phase is over, and you are ready to apply analysis and visualization pipelines to large datasets. This capability is useful in several contexts. ParaView provides Python scripting modules that cover all of the capabilities of the ParaView desktop application. Out_filename = output_filename_root + "%0.4d" % index +".Full visualization and analysis pipelines can be scripted and run without relying on the ParaView desktop application. The best way is either through a Programmable Source or by extending VTKPythonAlgorithmBase (which you got close to doing, you just needed to separate the class from the script, save it in a separate file, then load it as a plugin). In_filename = input_filename_root + "%0.4d" % index+".pvtu" Number_of_pvtu = directory(pvtu_input_directory,'.pvtu') """Choose input/output directory and filenames""" If file.endswith(extension): # eg: '.txt' Second, Python scriptscan be run inside pipeline objects, thereby performing parallel visualizationalgorithms. First,Python scripts can automate the setup and execution of visualizations byperforming the same actions as a user at the GUI. I run the script using execfile("SCRIPTNAME") in Paraview -> Tools -> Python Shell. Python scripting can be leveraged in two ways within ParaView. I had a similar problem with pvtu files and solved it with the script below.
