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!
