Inlet Boundary Conditions

At the inlet of the model there is a number of boundary conditions that can be prescribed. Depending on the machine type, data available and many more. There is always a set of boundary conditions for velocity and pressure at the same time. Turbulent quantities as e.g. kinematic energy of turbulence $\color{white} k$ , or e.g. rate of dissipation of kinematic energy of turbulence $\color{white} \epsilon$ they have more simple approach and are not dependent on the choice of velocity and pressure boundary conditions.

NOTE: Inlet boundary conditions are usually supported by boundary type patch, defined in the mesh file boundary.
