Convergence problems

I'm simulating a conjugate problem (heat transfer and laminar flow), where my domain correspons to a microchannel with ribs. I have been developed a paramteric analysis of the mesh from 100.000 to 3.200.000 DoFs. When I evaluete the convergence at the inlet of the domain, where I have imposed a boundary condition (normal inflow velocity), the velocity changes at the points of that part of the domain, mostly close to the boundary layer.
I think that the values of velocity at the points at of inlet are undepended or of the DoF and the values should be equal to the velocity inlet considering as boundary condition. Could this situation be related with two boundaries condition (inlet velocity and no-slip condition) are applying at the same region????
Thanks.
