You probably need to adjust your mesh at the tunnel walls in order detect the variation in velocity.

Compare the size of the cells at the tunnel walls with the boundary layer thickness. This...

Hi,

The options "default", "symmetry" and "periodicity" are settings at the minimum and maximum of the three coordinate axes of the Computational Domain.

The default velocity boundary condition...
