A 3D axisymmetric pipe in CFX

Ahmed Saeed Mansour · August 22, 2016, 14:39

Hello, I have an axisymmetric pipe in ICEM and I have defined the inlet, outlet and symmetry as a 2D edges, after the extrusion by rotation I have imported it to CFX but I cannot find these boundary conditions, what should I do?
Thanks

You need to define the edge faces as the boundary conditions, not the edges on the 2D surface before extrusion. CFX only recognises 3D faces.

Thanks, I will try it and tell you sir...

I have carried out the extrusion, now I am trying to create a part for the inlet edge but I cannot pick it from the monitor...Is there is another way?
Thanks
