Dear everyone,

I would like to map a random velocity field that I am generating artificially and is containing specific features that I need to a source plane of the same “dimensions” as the velocity field.

Could saving the data of the plane as a numpy array, modifiying it and then saving it back as a paraview readable object work?

Thank you all

You can try saving the velocity field as a `csv` file which is readable both by numpy and ParaView.

Yes indeed, I did that even if not in the most efficient way [here](https://discourse.paraview.org/t/applying-surface-lic-plugin-to-velocity-field/9514/6)
