Hi,
This may be a trivial question but I'm new to CFD. In CFX post you can plot surface streamlines. Given the fact that velocity is zero on solid walls (hence no streamlines there) what does this option represent? Also how can you get 2D views(x-y, y-z etc) in CFX post? Clicking on the axes don't work. Should these planes be defined? Thanks. Nick R |

Surface streamlines follow the wall shear stress vector.
To create 2D views put in a slice plane. Then you define the plane location and off you go. |

Thanks so it represents the shear force on the wall.

That's right. If you put an oil drop on the surface it is where the wind will blow it.
