Go to the Report -> Volume integral -> sum -> Discrete Phase Model, then calculate the sum for:

DPM mass source
DPM enthalpy source

the DPM mass source sum should be algebraically equal to the mass imbalance in the Report->flux panel
the DPM enthalpy source sum should be algebraically equal to the energy imbalance in the Report->flux panel

Of course, this happens at convergence. For large combustion problems, this energy balance can take longer to achieve and is a better indication of convergence than only relying on residuals.

Hello,

I am running multiphase simulation with DPM tracked as Lagrangian. In the simulation, heat and mass transfer from discrete phase to the continuous phase takes place. I can not get correct mass and energy balance in the Fluxe report. Can anyone help me?

Thanks.
