-This data setup are used to define the outflow condition features. The outflow geometry is restricted to rectangular/line forms in 3D/2D configuration. In the particular case of cylindrical geometries, the outlets can be circular, annular or bowed retangular. In fact, the geometry of the outlet fits the grid topology.\\
