Hello Foamers,

I am trying to explore the performance of the new multiphaseEulerFoam (OF 2.1.0), but in the beginning I found a mystery behaviour in the basic damBreak4phase tutorial case.

The problem is in time 5.75s, until that time the flow is stable, the column colapses and the mixture is trying to stabilize (loose kinetic energy) and separate by density.
(T = 0.00s, T = 0.15s, T = 5.70s)


But in time 5.75s the nearly stabilized mixture vanishes into thin air.


I don't suppose that I am the only one who knows this problem. I faced it from time to time in the last year when I was exploring the bubbleFoam and interFoam but I never found an example this ilustrative to solve.

So does somebody know what is wrong in such case? What can I try to correct?

Thanks in advance, for any hint.
Martin.
