-   * A complete set of wall boundary conditions, defined by a **WBCP**, is implicitly ranked by the order of appearance in the data file (RANK= order of appearance). As a consequence, unlike many other namelists, the order of appearance of each **WBCP** in the data file is crucial. The first set of **WBCP** is ranked 1, the second set is ranked 2 ....  (see examples below). +   * A full set of wall boundary conditions (**"WBCT"**) is created when the namelists related to the heat, velocity or species have got the same name, namely when the common variable 'Wall_BC_DataSetName' is set with the same character string (see examples below). 
-   * Each immersed body, whose geometry is defined by a **IBD**, has to be linked to one of the complete set of boundary conditions **WBCP** defined in the data file. The link is prescribed by the variable "Identifier_Value" of the **IBD**. The "Identifier_Value" must thus be set to the value corresponding to the rank of the choosen **WBCP** in the data file (Identifier_Value=RANK_of_Choosen_WBCP).  +   * Each immersed body (**IBD**) has to be linked to one of the **WBCT** defined in the data file. The link is made by means of the variable 'Wall_BC_DataSetName' belonging here to the namelists [[sunfluidh:polyhedral_immersed_bodies_setup_namelist|"Polyhedral_Immersed_Bodies"]] or [[sunfluidh:cylindrical_immersed_bodies_setup_namelist|"Cylindrical_Immersed_Bodies"]]. This variable must match with these ones of the namelists [[sunfluidh:heat_wall_boundary_condition_setup_namelist|"Heat_Wall_Boundary_Condition_Setup"]], [[sunfluidh:velocity_wall_boundary_condition_setup_namelist|"Velocity_Wall_Boundary_Condition_Setup"]] or [[sunfluidh:species_wall_boundary_condition_setup_namelist|"Species_Wall_Boundary_Condition_Setup"]]. 
-   * The walls placed at the ends of the domain are always linked to the first **WBCP** that appears in the data file.  +   * The walls placed at the ends of the domain are always linked to the **WBCT** whom Wall_BC_DataSetName= "Set1". 
-   * Differents **IBC** can be linked to the same **WBCP**, so that you may have less **WBCP** than **IBC** in a data file (to prevent any redundant **WBCP**). +   * Differents **IBD** can be linked to the same **WBCT** in order to prevent any redundant **WBCT** in the data file. 
 +   * The explicit setting of a namelist can be omitted if the physical quantity is not required in the simulation. For example : 
 +       * For any case without multi-species fluids, the namelist [[sunfluidh:species_wall_boundary_condition_setup_namelist|"Species_Wall_Boundary_Condition_Setup"]] can be omitted. 
 +       * For any case without thermal transfer, the namelist [[sunfluidh:heat_wall_boundary_condition_setup_namelist|"Heat_Wall_Boundary_Condition_Setup"]] can be omitted. 
 +   * If an usual boundary condition are used for __**all the walls**__ of the geometrical configuration, the associated namelist can be removed. For example : 
 +       * For adiabatic walls the namelist [[sunfluidh:heat_wall_boundary_condition_setup_namelist|"Heat_Wall_Boundary_Condition_Setup"]] can be removed. 
 +       * For no-slip and impermeability conditions, the namelist [[sunfluidh:velocity_wall_boundary_condition_setup_namelist|"Velocity_Wall_Boundary_Condition_Setup"]] can be removed. 
 +       * For no wall effect on species (zero gradient condition),  [[sunfluidh:species_wall_boundary_condition_setup_namelist|"Species_Wall_Boundary_Condition_Setup"]] can be removed.

-   * The first **WBCP** is automatically linked to the walls of the domain end's (cavity walls). The wall temperatures are imposed as in the previous case. Moreover the I-velocity component is set to 1.5 at the top wall (Front_Wall_Velocity_I= 1.5). +
-   * The bar (immersed body) is linked to the second **WBCP**. The usual no-slip and impermeability boundary conditions are explicitly stated here because the default values are no longer available due to the previous **WBCP**. +
-   * When several **WBCP** are present and at least one of them contains a specific set of velocity boundary conditions, which differ from the usual ones, the namelist [[sunfluidh:velocity_wall_boundary_condition_setup_namelist| "Velocity_Wall_Boundary_Condition_Setup"]] must then be explicitly set for each **WBCP**, even for the usual velocity boundary conditions. +
