===== Namelist "Temperature_Initialization" =====
This data setup is used to define the initial temperature field over the domain for flows with heat transfer.\\
This namelist can be removed for isotherm flows.

===== Full data set of the namelist =====

   &Temperature_Initialization Temperature_Reference_Value    = 293.0,
                               Initial_Field_Option_For_Temperature= 0 , 
                               White_Noise_Magnitude_For_Temperature= 0.0 /

<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>

===== Definition of the data set =====
-----
==== Temperature_Reference_Value ====
   * Type : real value
   * Reference temperature value.
   * Default value must be set by the user

==== Initial_Field_Option_For_Temperature  ====
   * Type : integer value
   * Option to define the distribution of the temperature over the domain :
     * 0 : Uniform distribution
     * 1 or greater : Optional values associated to temperature field defined by the users in the appropriate fortran module (see module_user_define_init_fields.f90). The reference value can be used to define the temperature scale. 
     * Default value = 0
 
==== White_Noise_Magnitude_For_Temperature ====
   * Type : real value
   * Magnitude of the white noise on the temperature field.
   * The magnitude is defined as a fraction of the local value in each cell ( i.e. 0.4 corresponds to 40% of the local value of temperature on the grid)
   * Default value = 0
