Hi, Am using reacting modell and langarian multiphase. Am injecting the char particles at the inlet the same with my a gas.The gas is continous phase and the particles are dispersed phase. My quastion is that are the multiphase modells or physics are the same as the

continuum physics modell? for example the energy conservation or mass conservation in the main modell is chosen then when i choose modell multiphase, it appears as it has its own modell inside the multiphase modell. why is that?
