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.

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.
