A strange streamline close to the wall

alimea · April 5, 2022, 23:05

Hi everybody
I want to plot streamline of secondary flow structures in a curved-duct that was simulated using OpenFOAM in a special cross section. I used the streamtracers tool in tecplot. However, the streamlinesclose to the inner and outer walls is strange! I don't know why, and I don't know how to report the secondary flow structures in my paper.
I will appreciate any answer that can help me!

Could you superimpose the geometry and plot few lines? The case is 2d?

Thanks for your reply Filippo
The case is a 3D curved channel.
I cannot plot a few lines. Do you have a way for that?
