Hi,

I have ParaView 5.6 and a bunch of `pvtu` files on a server to visualise. These contain high order data and I want to extract data over a line using a script.

I have a working script for the default case (linear cells). According to [this](https://github.com/dealii/dealii/wiki/Notes-on-visualizing-high-order-output) wiki page, Nonlinear Subdivision Level has to be manually set to visualise the high order data.

So my question is how can I do this setting through a paraview-python script?

P.S. I cannot use Trace Recorder for this on my personal device because it doesn’t support the required paraview version for high order visualisation.
