For MODFLOW, PHAST, and WellFootprint models, ColumnCenter({Column}) returns the X coordinate in the grid coordinate system of the center of the cell (MODFLOW) or element (PHAST) specified by its one optional argument Column. If the optional argument is not included, the function uses the column number of the cell or element for which the formula is being calculated. If an invalid column number is specified, ColumnCenter returns 0. For SUTRA and MODFLOW 6 DISV models, ColumnCenter returns zero.
