How to establish a gas-liquid-solid three-phase flow model?

Hello, researchers. I am learning to use MFiX to simulate gas-liquid-solid three-phase flow, but I am running into some difficulties. At present, I have mastered the simulation of liquid-solid or gas-solid two-phase flow, but the model of gas-liquid-solid three-phase flow has not been successfully established. Can MFiX be used to simulate gas-liquid-solid three-phase flow? If so, where can I obtain relevant study cases? Looking forward to your reply. Thank you!

MFiX only supports a single fluid phase, so the type of simulation you describe is not possible with MFiX.
