Hello!

I am trying to run a RANS simulation on NACA0012 airfoil using INC_RANS available with SU2 7.0.1. Tecplot 360 is the software that I am using to view the results.

Weirdly, for Angle of Attack=20°, the streamlines r observed to terminate at the lower surface of the airfoil and re-emerge from the upper surface, for some sections of the airfoil.

I wish to know what might be the cause of this discrepancy and how could it be overcome.

Thank you!
