Axial Velocity Contour in non-planar bend

omidmd · March 16, 2014, 07:04

Hi guys,

I simulated a fluid flow in a non-planar bend in which the inlet and outlet surfaces are not placed in the same plane. The bend consists of two 90 degree bends. I would like to see axial velocity in different sections along the pipe in CFS-Post.
I could have seen total velocity contour, but my problem is in plotting axial velocity. The axial vector is not along coordinates, but I have the normal vector at each plane.
Do you have any idea how to get axial velocity contour via CFD-Post?

Thanks,
Omid.

You could define a local coordinate frame at each point to get the axial component.

hi guys
could you please explain more what I have to do to plot an axial contours in non planar 3D curved pipe in different sections?
