-The user finds here some examples illustrating the construction of the wall boundary conditions.
-<WRAP info>
-   * A 2D geometrical configuration is considered. So, data associated to the 3rd direction K could be removed. They are still kept in these examples even if they are useless.

-<WRAP info>
-   * The domain is a square cavity (2D geometry).
-   * Bottom and top walls are insulated. The heat flux is null.
-   * The left wall is set to the upper constant and uniform temperature : T= 305K.\\ The right wall is set to the lower constant and uniform "temperature : T= 295K.
-   * The velocity boundary conditions are no-slip and impermeability conditions.
-   * There is no immersed body.
-   * Walls of the cavity are located at the ends of the domain. This is the basic domain configuration initialized by the code if any other boundary condition is not placed at the ends (like inlet, outlet, symmetrical or periodical boundary conditions, see namelists [[sunfluidh:inlet_boundary_conditions_setup_namelist| Inlet_Boundary_Condition]], [[sunfluidh:outlet_boundary_conditions_setup_namelist|Outlet_Boundary_Condition]], or [[sunfluidh:border_domain_boundary_conditions_namelist_setup|Border_Domain_Boundary_Conditions]]).

-   * 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.
