  * '''''mX(3)''''':  The grid's overall size.  Each element {{{mx(n)}}} represents the number of cells along the ''n''th dimension.
- * '''''Xlower(3)''''':  The spatial coordinates of the grid's lower bound in each dimension.  These values are ''always'' given in computational units.
- * '''''dX(3)''''':  The size of a spatial step in a given dimension.  {{{dX(n)}}} can also be thought of as the size of a cell along dimension ''n''.

-To make this example more readable (and therefore easier to debug), we assigned the various array values more Cartesian-sounding names (ie., {{{Info%dX(2) = dy}}}).

 Similarly, when calculating the spatial equivalents of an index, we went with {{{x}}}, {{{y}}} and {{{z}}}.  The half-step in the position calculations represents the fact that the spatial position is at the ''center'' of the cell, not the left side.
