aarratia New Member arrmando Join Date: May 2014 Posts: 16 Rep Power: 12	hi guys, I am trying to simulate an empty container (air inside) which then is filled with water using bot inlet and outlet using Volume of fluid model. My question is Which liquid /gas should be my primary and secondary phases? also When I add the inlet velocity I can only pick Mixture instead of just water. Why is this? (I have already entered this is a 2 phase VOF). I have the same problem with the outlet I can choose air or water but I can not seem to pick one or the other. When I choose air phase, lets say for outlet all my other boundary conditions inlet and water outlet change to air phase. Is there something I am missing during setup? Why is this? Your help is greatly appreciated. Best regards, AA
