Hi,
the problem is that you defined in pre-processor (when you built the geometry) all the sides as "wall" boundary condition (white edges).

Instead, the problem is 2d axisymmetric, with a pressure inlet and a pressure outlet boundary conditions.

So, go back to the pre-processor and assign correct boundary conditions.

Dear All,

In Fluent > General > Mesh Display,
I have only 2 components, actually it should be 5 components

Same issue; re-read my answer.
I suggest to begin reading tutorials about mesh generation.

Thanks Daniele,

I do as you mentioned, now I can get 5 components in boundary conditions, but in Mesh Display I still have only 2 surfaces.

I try to find the tutorial on the internet, but I can not solve this problem

Thank you in advance
