The number of grid cells in x, y and z, the filename, and the units are specified in the Grid Card and must match what is specified in the generic eclipse file. The minimum z-direction spacing is specified to avoid overlapping layers and negative cell volumes.

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.
