Info

The first value must be the cell surface location, but after that, either the cell surface or the count@cell size may be specified.

For non-uniform grids, the location of the cell edges is specified, therefore, the number of cell surfaces specified will be one more than the number of grid cells in that direction.

Tip
 The grid dimensions that are specified on the Grid Card refer to node surfaces; therefore, for grids with non-uniform spacing, for each grid direction the number of entries required is one plus the number of nodes.  Node volumes are defined by their bounding surfaces. Cylindrical coordinate systems are restricted to azimuthal axes which are less than or equal to 360 degrees.
