 This data setup is devoted to the selection of the numerical methods and schemes used in order to solve the conservation equations for velocity components, temperature, species mass fractions and density (in particuliar cases) and Poisson equation for the pressure. Some parameter setting could be also considered in respect with the numerical method selected. This data setup is devoted to the selection of the numerical methods and schemes used in order to solve the conservation equations for velocity components, temperature, species mass fractions and density (in particuliar cases) and Poisson equation for the pressure. Some parameter setting could be also considered in respect with the numerical method selected.
 +The data are divided in three groups in order to define :
 +    * the numerical method applied for solving the conservation equations (for velocity, temperature, species, ...)
 +    * the choice of advective or convective flux discretization (for 2nd order schemes). the viscous, conductive or diffusive fluxes are always discretized with a centered 2nd order or 4th order scheme according to the previous choice.
 +    * the numerical method (and associated parameters) for solving the Poisson's equation according to the type of problem considered. several methods are presented based on direct or iterative approaches.

-Two versions of the data setup exits. This is related to the newer release of the code. \\ __** Not for the release SUNFLUIDH_EDU**__+This version allows the users to select the numerical methods by means of characters strings instead of option numbers. For sake of clarity, the iterative method parameters used for the solving of Poisson's equation are defined in two individual namelists 
 +   * HomeData_PoissonSolver for methods directly implemented in the code (homemade) 
 +   * HypreData_PoissonSolver for methods implemented in the HYPRE library
