Default InterFoam: Error

Kappa is on a distinguished road
Hey everyone,

I'm using interfoam and the k-omega-SST model so as to simulate multiphase, turbulent flows.

Sometimes OpenFOAM exits returning a Floating Point Exception. Decreasing the step size solved this problem but it ended again in this exception after some iterations. I increased the step size again and it worked! (till now, I do not know if it will work the whole time now)

WHY is this solver so sensitive towards step size and where does this problem come from? I would somehow like to fix it because now simulations always blow up over night and do not finish till morning.

Thanks for help
