Hello everyone.

I'm simulating a flow in a Venturi tube, I simulated the flow as an axisymmetric problem with simplefoam and I got a good performance but when I ran the case in 3D the flow behave strangely. I have changed the resolution of the mesh but not work.





I leave two pictures about the problem and my mesh.

If someone can explain me why occurs this behavior, I'd appreciate the help.

Thanks.
