Hello,

I am trying to run the damBreak case with two fases (air and water) with multiphaseEulerFoam. When I use the mixtureKEpsilon model works ok, but if I use the kEpsilon or kOmegaSST dont run, stops in the first cycle. Someone can help? The case is attached.

Other question is about diameter of the phases. The results seens very sensible to this parameters, the fluid with high values (1e-4) of diameter seens more viscous. Anyone has a good documentation about this? I cant found a good one.

Thanks.
