BlockVolume

For MODFLOW and PHAST models. BlockVolume({{Column, Row,} Layer}) returns the product of the length, width, and height of an element or cell. For three-dimensional SUTRA models, BlockVolume returns the volume of the cell or element. For two-dimensional SUTRA models, BlockVolume returns zero. The function has three optional arguments: Column, Row, and Layer. If these three arguments are provided, they specify the element or cell for which the volume should be calculated. If they are not provided, the function uses the column, row, and layer of the node or element for which the formula is being calculated. If only one argument is provided, it is treated as the layer. If any of the three arguments has an invalid value, the function returns zero.

For SUTRA and MODFLOW 6 DISV models, Row should always be 1 and Column represents the cell or element number.
