      Just us following expressions to sum up the positive or negative mass flow rates through the cells of an arbitrary plane with name “Surface”: Positive mass flow rate: areaInt(max(0.0[m/s],Velocity u * Normal X + Velocity v * Normal Y + Velocity w * Normal Z)*Density)@Surface Negative mass flow rate: areaInt(min(0.0[m/s],Velocity u * Normal X + Velocity v * Normal Y + Velocity w * Normal Z)*Density)@Surface
