Hi
I am running a 3D VOF model including k-e turbulence equations. The laminar solution of this model is used as the initial solution. Thus, initially, the imbalance between the two water and air inlets is zero. Unfortunately, over the course of run, the outlet mass flow is absolutely decreasing and the imbalance between inlet and outlet is increasing.
Do you have any idea?
Many thanks
