Try the tutorials/multiphase/multiphaseEulerFoam/RAS/bubblePipe It looks like your case is incorrectly setup and you will need to arrange support. |

Hello Henry, The tutorial bubblePipe has only 2 phases, in addition the gas phase is set to laminar in the tutorial. I have 3 phases all highly dispersed and wanted to have turbulence effects for all phases. I will try the kOmegaSSTSato with 3-phase and report back and maybe also expand the bubble pipe to 3-phase. Regards Jason |

I have extended the tutorial multiphase/multiphaseEulerFoam/RAS/bubblePipe to 3 phases. I have set kOmegaSSTSato for both liquids and left the gas phase as it was. Also, split the alpha liquid between the two liquid phases. If I set the gas phase to laminar the case runs, if I set the gas phase to RAS I get the same error as reported at the end of the first post above --> FOAM FATAL ERROR: Call from a two-phase model in a multi-phase system. From function const Foam::phaseModel& Foam::phaseSystem::otherPhase(const Foam::phaseModel&) const in file ../phaseSystems/lnInclude/phaseSystemI.H at line 118. FOAM exiting It seems that I cannot set turbulence for 3-phases Regards Jason |

kOmegaSSTSato is specifically a 2-phase model. |
