Velocity Inlet
The velocity inlet boundary type requires the following boundary conditions when the K-Epsilon turbulence model is active:
The following boundary values are also required:
- Turbulent dissipation rate.
This is only available if the Method property of the Conditions 
Turbulence Specification is set to K + Epsilon. - Turbulence intensity.
This is only available if the Method property of the Conditions Turbulence Specification is set to Intensity + Length Scale or Intensity + Viscosity Ratio. - Turbulent kinetic energy.
This is only available if the Method property of the Conditions Turbulence Specification is set to K + Epsilon. - Turbulent length scale.
This is only available if the Method property of the Conditions Turbulence Specification is set to Intensity + Length Scale. - Turbulent viscosity ratio.
This is only available if the Method property of the Conditions Turbulence Specification is set to Intensity + Viscosity Ratio.
