jester09 is on a distinguished road
I was trying to simulate a cavitating flow(2D) around naca 0015 in FLUENT(version 6.3.26). The mesh was generated in GAMBIT and i guess it is quite perfect. But the problem arises when i make iteration in fluent. For a cavitating flow most of the areas of the domain should show the vapor fraction as 0 when the display (contour of phase(vapor)) is selected. Only there will be a small area where it will show the generation of some vapor. But in my dat file it has been shown that the vapor fraction is above 0 in everywhere of the domain.The first figure is the desired result while the second one is the consequence of my simulation which isn't correct. I will be grateful if anyone help me in this circumstance.
