Hello Mathieu,

I have tried the files you uploaded but I get a huge error like seen in the attached screenshot. Do you have an idea what the problem could be?

I also tried to reproduce the example with the disk\_out\_ref data shown in the pictures of the release blog entry in the following link:

> Hi, I learnd there is a LagrangianParticleTracker from [https://blog.kitware.com/vtk-and-paraview-add-highly-configurable-particle-tracker/](https://blog.kitware.com/vtk-and-paraview-add-highly-configurable-particle-tracker/), so are there some examples files or other materials I can used to learn the using of the LagrangianParticleTracker? Thank you!

Unfortunately, I didn’t get it. Maybe you could add the steps in the description of the link?
