The volume, sum, maximum, minimum, volume integral, volume-weighted average, mass integral, and mass-weighted average can be obtained for a selected field variable in selected cell zones in the domain.
Example uses of the different types of volume integral reports are given below:
Volume: You can compute the total volume of a fluid region, or the volume of a phase within the fluid region.
Sum: You can add up the discrete-phase mass or energy sources to determine the net transfer from the discrete phase. You can also sum user-defined sources of mass or energy.
Sum*2Pi: In a 2D axisymmetric model, you can add up the discrete-phase mass or energy sources to determine the net transfer from the discrete phase in the entire revolved domain. You can also sum user-defined sources of mass or energy. This report type is only available in 2D axisymmetric cases.
Maximum: The maximum value of the selected variable among all cells in the selected zone.
Minimum: The minimum value of the selected variable among all cells in the selected zone.
Volume Integral: For quantities that are stored per unit volume, you can use volume integrals to determine the net value (for example, integrate density to determine mass).
Volume-Average: You can obtain volume averages of mass sources, energy sources, or discrete-phase exchange quantities.
Mass Integral: You can determine the total mass of a particular species by integrating its mass fraction.
Mass: You can determine the total mass of the mixture phase or an individual phase in the selected fluid zone.
Mass-Average: You can find the average value (such as average temperature) in a fluid zone.
