I am trying to plot the streamlines like the left figure but the figure i am trying the output is the right one. The streamlines of the back of the building is not same. How can i plot stream line like the left one in paraview.

Thanks in advance.

Thank you very much. But this works only for 2d flow feature. but my streamlines are 3d. i am not able to apply it in 3d flow feature. can you please give me any information for 3d streamlines?

Yes, indeed this works only for 2D. We don’t have anything similar for 3D as far as I know.

I was planning to see this type of streamline in my scour simulation
