+The turbulence boundary conditions have a `MARKER_INLET_TURBULENT` keyword for the Turbulence models. For the SA turbulence model, ratio of turbulent to laminar viscosity can be provided at each inlet as follows:

-The Species transport is switched on by setting `KIND_SCALAR_MODEL= SPECIES_TRANSPORT`. For the mass diffusivity, the following models are available `DIFFUSIVITY_MODEL= CONSTANT_DIFFUSIVITY, CONSTANT_SCHMIDT, UNITY_LEWIS, CONSTANT_LEWIS` , where `CONSTANT_DIFFUSIVITY` is the default model. For the first two, a constant value must be specified in the.cfg file for all species, as it is done in the species transport tutorial [Inc_Species_Transport](/tutorials/Inc_Species_Transport/). For the UNITY_LEWIS, no values must be provided because the diffusivity is computed using the mixture thermal conductivity, density and heat capacity at constant pressure; for more information, please see $^{3}$. For highly diffusive gases, such as hydrogen, the `CONSTANT_LEWIS` option could be used. For this option, the Lewis numbers of the N-1 species for which a transport equation is being solved must be provided as a list using the option `CONSTANT_LEWIS_NUMBER= Le_1, Le_2, ..., Le_N_1`. Finally, for turbulent simulations, the turbulent diffusivity is computed based on the `SCHMIDT_NUMBER_TURBULENT`. For reference, please consult [the respective theory](/docs_v7/Theory/#species-transport).

 Finally, for the SST model, it is possible to provide the intensity and turbulent-to-laminar viscosity ratios per inlet. For this option, we use the following structure: `MARKER_INLET_TURBULENT= (inlet_1, TurbIntensity_1, TurbLamViscRatio_1, inlet_2, TurbIntensity_2, TurbLamViscRatio_2, ...)`.  
 
-As final remarks, the option `SPECIES_USE_STRONG_BC` is advised to be set to `NO` when the convective scheme for species and turbulent are `CONV_NUM_METHOD_SPECIES= BOUNDED_SCALAR` and  `CONV_NUM_METHOD_TURB= BOUNDED_SCALAR`, respectively. When `SCALAR_UPWIND` is used in both cases, the `SPECIES_USE_STRONG_BC`  is advised to be switched to `YES` to enforce boundary conditions and improve convergence for this convective scheme. The convective scheme `BOUNDED_SCALAR` will be further explained in the section [Convective-Schemes](/docs_v7/Convective-Schemes/).

 Likewise, `SPECIES_CLIPPING= NO` is only recommended when the option `SCALAR_UPWIND` is used. The option `BOUNDED_SCALAR` performs well without using the clipping option.
