 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]]).
-===== Namelist statement =====
-Few things to know about the namelist statement :\\
-The NAMELIST statement defines a group of variables or arrays. It specifies a group name, and lists the variables and arrays of that group. The namelist starts with a & directly followed by the name of the namelist and ends with the / character.   For instance :
-    &Fluid_Properties    Reference_Dynamic_Viscosity= 1.84D-05, ! a comment can be written here
-                    Reference_Density= 1.19, Reference_Temperature= 293.0, Prandtl= 0.72 /
-Here the variable Reference_Density in the namelist Fluid_Properties is set to 1.19. In input3d.dat, a namelist or some variables in a namelist can be ommitted according to the context. For instance, for a numerical simulation without heat transfer, the namelist Fluid_Properties can be reduced to :
-    &Fluid_Properties    Reference_Dynamic_Viscosity= 1.84D-05,  Reference_Density= 1.19 /
-This allows us to define the simulation setup only from the useful data. If they are not set in the file input3d.dat, the data are initialized with default values. \\
-The entire set of input data  (default and user's values) are written in the file check_namelist_data.dat by sunfluidh at the beginning of each run.
-<note important>BEWARE : A same namelist can be used several times in the data file in order to initialize different physical quantities belonging to a same type. For instance, if you want to initialize the physical properties of different species, you will use the same namelist (named Species_Properties_Namelist, see below) for each species. When a namelist could be used several times, the last must contains the variable End_of_Data_Block = .true. in order to specify the end of the namelist series.</note>
-Example :
-   &Species_Properties      Species_Name = "H2" , .... /
-   &Species_Properties      Species_Name = "O2" , .... /
-   &Species_Properties      Species_Name = "N2" , ...., End_of_Data_Block = .true. /
-The first namelist contains the group of data describing the properties of the di-hydrogen, the second for the di-oxygen and the third for the Nitrogen. Only the last namelist contains the variable End_of_Data_Block = .true.
-If only one species is initialized, the namelist must however contain the variable End_of_Data_Block = .true.
