Hi,

The mass of a particular phase is computed by summing the product of phase density, cell volume, and phase volume fraction.

The mass-weighted average of a quantity is computed by dividing the summation of the product of density, cell volume, and the selected field variable by the summation of the product of density and cell volume.

**Mass**: You can determine the total mass of the mixture phase or an individual phase in the selected fluid zone
