in vertical falling film,the flow should be parabolic.but in fluent,how i can get this profile.there are four boundary conditions:liquid velocity inlet,liquid pressure outlet,vapor pressure inlet and wall.thanks!

Did you tried to set up velocity inlet BC with profile instead of constant value?

What do you mean "finish"? What problem do you have with velocity profile?
