I am using Volume Of Fluid(VOF) model. For outer boundary i have to give air as a fluid which is not a part of mixture or VOF model. So please help me how to give air without incorporating in VOF model. Thank You....

I am afraid your question not clear how you want to apply vof model without including air? may you give more details about your problem supported with sketch?

hi, i have the same problem, with two phase (water-liquid + water-vapor) with species transfer (liquid to vapor), i had patched water-liquid already; but still shows no water-vapor. somehow, i can't figure out, what's the major problem is ?

thanks all, i will wait with hopes.

there are some other setting items of volume of phase on initialize and boundary conditions. just try enter different setting then see what happens.Good luck!!
