Hi,
I want to know what stream line option will give the velocity streamline plot as shown in the figure below. I want exactly the same view, please help.

Thank you

Regards
Hamed

That looks like streamlines seeded at the inlet, with one seed per element. The mesh is biased to be finer next to the wall so the streamlines get finer next to the wall. They are coloured by velocity.

It's probably what Glenn said, but you should try to mess with the seeding options, there's a few of them, including a seeding line that could generate an plot similar to the one you want, at least when you look it by its side view.

What probably would change regarding the mesh refinement are the colors. As you may know, a finer mesh should give you more information about any given property hence more colors.

Correct if I'm wrong!

Good luck

It is telling it where to sample the seed points from on your starting face.

I saw you PMed me, did you find the "line" (edge) I told you about?

I confused line with edge i guess! Sorry about that.

I see you've got nice results!
