- Void Fraction
- The fraction of the cell volume available to the fluid, unoccupied by a solid or dispersed phase.
- Volume
- This field function contains the volume of each cell.
- Volume Change
- This field function describes the ratio of the volume of a cell to that of its largest neighbor. A value of 1.0 indicates that the cell has a volume equal to or higher than its neighbors. A large jump in volume from one cell to another can cause potential inaccuracies and instability in the solvers. Investigate cells with a volume change value of 1e-05 or below as they can be considered suspect.
