Description	Large Eddy Simulations of backward facing step were performed. One of the difficulties of Large Eddy Simulation is correct representation of the turbulence on the inlet to the region. Therefore the simulations were done using different approaches to the inlet boundary condition. The impact of the choice of inlet boundary condition treatment on the fluid flow is consequently studied. It has shown, that using uniform velocity profile on inlet and even prescribing turbulent mean velocity profile without proper representation of turbulence fluctuations leads to unrealistic results. The only approach used in this work which gives sufficiently accurate solution is direct mapping of velocity from plane positioned behind the inlet back to the inlet.
