alpha1 decrease while using interFoam

afo3 · November 23, 2010, 10:29

hello everybody,
I'm trying to study the resistence of a ship with interFoam (or better, a modified version of it).
I'm using a half model in a volume of control with a symmetry plane and an inlet and outlet patches.

during the simulation, I noticed that the liquid phase volume fraction continually decrease, in other words, I'm loosing water

could it be due to boundary conditions?

thanks for your help

Michele

I am simulating an agitated vessel with interDyMFoam and have the exact same problem, the alpha value continuously decreases. I have checked the tutorial provided in OpenFOAM and the exact same problem occurs. Did you ever fix this? Has anyone else had this problem?
