===== 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 ===== Namelist lookup list ===== Click on the highlighted namelist to get more details about it (type of data, definition of data,...) ^ Fluid Properties ^^ | [[
