Hi guys! I managed to simulate the 2D couette flow using periodic boundary conditions in SU2,but I can't do it right for 3D case. You can see the errors in the attachment.

Also, how to set multiple groups periodic BC.
I think it would be like that.
MARKER_PERIODIC= (left,right,0,0,0,0,0,0,0,1,0,back,front,0,0,0,0,0 ,0,1,0,0)
but it's not right.

Hope someone with experience can help me.
