Practicle Tracking in Paraview (DualSPHysics Lagrangian output/ VTK file)

Hi there.
Thank you for your consideration.

I have run into a problem while trying to use a streamline/particle tracer filter in ParaView with the DualSPHysics output.

Hi there.
I want to track the particles using ParaView around my square pier, in a 3D dam-break case, which I simulated in DualSPHysics

I can import the VTK files and plot the velocity vector in 3D. But when I go to use the streamline or particle tracing filters nothing shows up in ParaView. Furthermore, when I look into spreadsheet viewer I don’t see any data.

Is there any way special way to particle tracking?

Thank you
