Why does the fluid flow not grow but only stagnate in Polyflow?

My problem is described as below in the diagram. The problem I set up is the isothermal flow problem of Newtonian fluid.
The material I use here is water with a density of 998.19 kg/m^3 and an entered Newtonian viscosity of 0.0010053 Pa.s. Geometry is symmetrical
The boundary conditions I set up are:
Inlet: Q = 1.26705E-05 m^3/s
Wall: Zero wall velocity (vn = vs = 0)
Outlet: Outflow
Axis: Symmetry axis
Results: According to the vector chart, the fluid flow is physically correct, the flow does hit the wall and goes out the outlet. But according to the counter chart, the line does not develop completely, it only develops a little and then stops completely.
