Hi freinds , I've a problem regarding the boiling of a cryogen in a tank in ANSYS FLUENT 13.0

Problem description in brief: A cylindrical Tank is inially filled with Liquid Nitrogen . A constant heat flux is given on the bottom side of the tank. On the top of the cylinder a small pipe is fixed for flow of gaseous nitrogen.
I've used VOF multiphase, Standard K-epsilon model.


During Calculation ,the problem arising is..

1) Mass flow rate graphs showing a negative trend with respect to flow time( I need to find out the mass flow rate for a few seconds say 10sec)




Eagerly waiting for a reply to the solution of this problem..
