axisymmetric case
I'm trying to simulate a simple problem  current in a pipe of constant diameter. Tried manually and using the utility makeAxialMesh to create axissymmetric case. After start simpleFoam solver there are deduced data for 3 vector components.

That is two components should be deduced only. Even, if display data of 3 components it is normal for an axissymmetric of projects, there is one more problem  the component of velocity Uz for quasiempty dimension most worse to converge. What to do? 
Well, I'm not sure what your exact problem is ...
Can you be more specific? 
It is normal that all three components are still displayed, as the grid is still 3D (just with special cells and boundary conditions). And about Uz: Is it maybe possible that you mixed up X and Z direction during mesh generation (so that Y and Z span your computational plane and X is normal to the side of the wedge)? Did you look at your mesh in paraview to make sure everything is correct?

Can look and prompt why badly to converge quasiempty component of velocity Uz. Here the project:

Well all right, then can, somebody even to show a correct ready example stationary axialsymmetric flow?

Which solver are you using?

simpleFoam.

Your case doesn't run for me using simpleFoam. I assume you are using 1.6 and I'm still on 1.5, so I can't really help you.

I have installed OpenFoam 1.5. Hardly has altered the project. The problem is considered. But the quasyempty direction of viscosity Uz is bad to converge.
