Hello,

I am new to using this library.

I have a bunch of \*vtu files which are part of \*pvtu generated from deal.ii. I want to make some changes to the point-data present - delete a few variables and add a few more manually through a python code. I also want to save these edited \*vtu files in the same structure - linked to a \*pvtu file so that I can take advantage of faster visualizations using Paraview running on a cluster.

I would like to have some recommendations that can run in parallel, because the mesh has 17mil points distributed over 192 \*vtu files for each timestep.

Thanks in advance,  
Raghunandan.
