Streamlines generation using polydata

Hi Bane Sullivan,

Thank you for the response.

As you said, I have created a point source with radius(2) and number of points(1500) and put this point source exactly at the center of my Domain. But with this also I cannot see any output.

Also I tried with LineSource without any luck.

I am attaching the outputs with PointSource and Line source which are placed inside the Domain below.

As my data is a Particle data(Contains only Points and Vertex (CellArray)) and doesn’t have any scalars, so I am injecting scalars to it. Is there anything that I need to do to my particle data?
