+The dimensionalization scheme can be set using the option `REF_DIMENSIONALIZATION`. For all schemes, the values set with `FREESTREAM_DENSITY` and `FREESTREAM_TEMPERATURE` are used as reference values for Density and Temperature, respectively, i.e. $$ \rho_{ref} = \rho_{\infty}, T_{ref} = T_{\infty}$$. The reference velocity is based on the speed of sound defined by the reference state: $$v_{ref} = \sqrt{\frac{p_{ref}}{\rho_{ref}}}$$.
