[Paraview] Fluid Flow Simulation in ParaView

[Rohit Narurkar]

Hello

I have one more doubt that I haven't found a detailed solution to online.
With the same vtk file (uploaded above), can I view the streamlines
distribution?
I know it has to do with the 'Stream Tracer' filter, but which parameters
do I use?

Thank you!
