 October 19, 2004, 01:20 phase changing simulation #1 David Liu Guest   Posts: n/a Sponsored Links Hello All i am working for vapor condensing in a duct ,and i want to solve this problem using VOF method. But i don't know if VOF can be used to solve this promlem. i hope someboby can tell me some information about this, and give some advice. thanks a lot. David Liu

Be careful how you discretise the terms to avoid the volume fraction solution to go out of bounds (0 <= gamma <= 1). Good luck, Hrv
