Example of border boundary conditions
Click here for the previous page
This example is defined for a 2D geometrical configuration. The size of the domain is $1.5 \times 1.0.$
An inlet is located at the down left side of the domain.
An outlet is located at the top right side of the domain.
A symmetrical plan is located at the bottom of the domain (Y=0)
We remind the user the domain is enclosed by default. Wall boundary conditions are implicitly defined at the ends of the domain.
The inlet and the outlet are built from the namelists
Inlet_Boundary_Condition and
Outlet_Boundary_Condition, respectively.
These boundary conditions replace the wall boundary conditions (default) over the areas defined in the namelists.
The inlet and outlets boundary conditions are presented herein for the sake of clarity.
The border boundary condition in accordance with the described configuration are shown just after the inlet/outlet conditions.
