Hi everybody

I study the turbulent flat plate and when I run the tutorial case in SU2 (V3.1.0), there is some stripes in the boundary layer. I don't understand why is there this strips. I tried to change the Reynolds Number from 0.2 to 0.3 and 0.4, and I change the grid for the case M=0.4, but the stripes are still there.

I attached to this message some picture of theses stripes, the different configuration files and my mesh for the case M=0.4 (I used the initial tutorials mesh 137*97 for the other cases).

I'm interested if you have some explication or the same things on this test cases.

Thank you in advance .

Regards,

Jeremy

I can't upload my Mesh because the size of the file is too big, but I attached a picture of this mesh, and the configuration files.
