 +<note important> For low Mach-number flows, the user must ensure the coherence between the reference values of physical quantities defined in the namelist [[sunfluidh:fluid_properties_namelist|"Fluid_Properties"]] (temperature, density and molecular mass), the initial temperature field over the domain (defined here) and, if needed, the species mass fraction distribution defined in the namelist [[sunfluidh:species_initialization_namelist|"Species_Initialization"]] (if the gas is composed with multi-components).\\
 +Keep in mind that the reference value of thermodynamic pressure is calculated from the reference values of temperature, density and molecular mass of the fluid (see namelist [[sunfluidh:fluid_properties_namelist|"Fluid_Properties"]]). \\ The density field is then initialized from the fields of temperature (and species mass fractions if needed) by considering the thermodynamic pressure is uniform over the domain (low Mach-number hypothesis).</note>
