as picture shows ,i do a 3d pipe flow,in order to save time ,i use axisymmetric model and axis boundary,how can i get a 3d view in post processing?

or my seting has some problem ,who have done this,can someone me how can i set in axisymmetric model? give me a case or give me a guide,thaks

is there someone can help me ,I am very anxious because of graduation

1) Be patient, answers don't come in 2 minutes...

2) why? a 3D plot does not contain more information than 2D, and is more difficult to evaluate.

1) thanks for your reply,This problem has troubled me for 3 weeks

2）3D contains more spatial information，Perhaps the axisymmetric model, the same information on each side，But I still want to know how to solve this problem.

3D contains more info if the geometry is actually 3D (in which case it would actually be easy to do the 3D plotting). Since your used geometry is 2D, there is no information gain by plotting in 3D - you are solely showing the same information in a more complex manner; I would strongly advice against using 3D plots in this case because all it does is obscure your results. Aside from that, I wouldn't know either. If FLUENT gives you a (small) pie-point section, then you can set periodic repeats under viewing (where exactly depends on the FLUENT version), but if you only have the 2D profile, that won't help. Perhaps MATLAB or another external viewer could do it in that case - but it's a lot of work for no gain.

Thank you for your kindness help, I understand what you mean, so I no longer pay attention to how to display 3D views.
