WitrynaAt the walls impermeability and no-slip boundary conditions are realized. Velocity components which are needed on the pipe axis, are obtained by interpolation across the axis. In the circumferential direction all variables are periodic by definition. In axial direction periodic boundary conditions are used, too.
