Hello,
I would like to make a dynamic rendering with this dataset.
Ideally, some arrows moving along the lines showing the wind/particule direction.
I’m not yet demanding with the accuracy of the analysis but at the technical possibilities.
Thanks in advance, Frank

There is a trick you can do with the `Contour` filter and the animation tracks to animate particles along the streamlines. I found an old post that describes how to do it: [https://www.paraview.org/Wiki/Advanced\_Tips\_and\_Tricks#Animating\_a\_static\_vector\_field](https://www.paraview.org/Wiki/Advanced_Tips_and_Tricks#Animating_a_static_vector_field)
The basic idea is as follows.
1. Add the `Contour` filter to your `Stream Tracer` filter. Set the `Contour By` filter to `IntegrationTime`.
2. Open the `Animation View` (`View` menu → `Animation View`).
3. Add an animation track for the `Contour` filter and the `Isosurfaces` property.
4. Increase the `No. Frames` to something larger (like 100) so that you have a smoother animation.
5. Hit play.
You should see some dots move along the streamlines. You can use the `Glyph` filter to to covert the dots to cones or arrows or whatever.
