Why can't my tracer line show up?

Hi, I am doing the research on dsmc. I use dsmcFoam to simulate the double lid-cavity. When I finished and try to have the stream tracer, it only shows a little line.

Please help me . Thanks a lot!

I don't know what DSMC is. Can you please explain a bit more about what you are simulating, on which part of the domain you need to visualise streamlines and what settings you used to make the streamlines? Are you sure that your mesh and boundary conditions are correct?

Maybe you can try making a slice of velocity with LIC instead of plotting streamlines?
