Thank you for your help! I thought that the Reynolds number was low enough to consider that the flow is not fully developed. So I have no reason to expect a parabolic velocity profile.

First of all, thank you very much for answering.
The reynolds number is around 340.
Respect to convergence, I first used residual values = 0.001, and then 0.0001. Convergence is always achieved....

i dont understand: grid validation - laminar flow

in order to validate a grid to simulate the laminar flow in a pipe (2D, diameter=5 cm, lenght=50 cm, inlet velocity=0.1 m/s), I have used five different grids:

Case 1: 40 elements
Case 2: 168...
