In a three-dimensional array (also referred to as a solid or block model), the dependent variable (g) is a function of the horizontal (x,y) and vertical coordinates (z). Grids are used to model topography, stratigraphic contacts, isopachs, and water levels, while solids are used to model geochemistry, ore grades, and geotechnical properties.
