I'm having problem with the definition of boundary conditions thorugh profile data.
The .dat file is uploaded well (image attached).
I choose "components" as velocity inlet, then i choose this profile as axial velocity inlet (the same for tangential and radial, with other profiles).

After initializating, when I plot the axial profile (contour plot) the maximum velocity is lower than in the profile boundary condition (around 3 m/s in the boundary, 1.3 m/s in the contour plot)

Why the velocity at the boundary isn't what it sould be?

Problem solved, the "r" distance should be specified in meters and not in mm
