I'm using Fluent6.2 to simulate film boiling problem.Firstly,I refer to the tutorial: Horizontal Film Boiling.But I cannot get the same results as the tutorial,did not bubble come into being. When it's 0.5 secends, there is rectangular vapor on the wall heater.Liquid is at the top of vapor. Have anyone got the same results as the tutorial?

Could anyone give me some hints?I am looking forward your reply.
