u can break B.C 2 and B.C 4 in to two boundaries while define them in Gambit. So u can handle better while air and water are separated. Then for water u can choose mass flow inlet and out flow, and for air u can choose both of them pressure outlet in the left and right side.
I'm here for more comments of others.
