===== SUNFLUIDH DATA SETUP =====
[[:start|Click here to come back to the previous page]]
-----

The file **input3d.dat** is the main data file to prescribe input values to sunfluidh. It contains the major part of data : geometric layout, flow features, boundary conditions, simulation management ...
Each part of the file is structured by means of the NAMELIST concept ([[namelist_statement|click here for more details]]). 

===== Content of the data file =====

Herein the user finds the content of the data file before addressing in details each namelist of the data set:

   * The fluid properties
     *  Physical properties of the fluid (incompressible fluids, low Mach number hypothesis, multi-components gas, two-phase flows, reactive flow) 
     *  The reference values of the main physical quantities.
   * Field initialization
     * Velocity
     * Temperature
     * Species mass fraction 
     * Two-fluids interface (density distribution with discontinuity)
   * Forces applied to the fluid 
     * Gravity and buoyancy force
     * Sustaining force, etc ...
   * Domain configuration
       * geometry of the domain
       * Immersed bodies characteristics (in order to build complex geometries)
       * domain decomposition methods (for parallel computing)
       * mesh characteristics
       * boundary conditions 
     * Simulation management
       * Numerical methods for solving equations
       * Numerical time step
       * time range of simulation
       * Stopping criteria
       * Backup files, checking files
       * recording rates of data acquisitions
     * Data acquisition
       * Time-series
       * Instantaneous fields
       * Statistics
