If KDZ = +1, read II * JJ * KK values (one for each block).

8. DZNET
DZNET Net gridblock thickness in z direction (ft).
If KDZ = -1, read one constant value.
If KDZ = 0, read KK values (one for each layer).
If KDZ = +1, read II x JJ x KK values (one for each block).

24.1.2 Modifications to Grid Dimensions

1. Heading Up to 80 characters.

2. NUMDX, NUMDY, NUMDZ, NUMDZN, IDCODE
NUMDX Number of regions where x direction grid size (DX) is
changed.
NUMDY Number of regions where y direction grid size (DY) is
changed.
NUMDZ Number of regions where z direction gross thickness (DZ)
is changed.
NUMDZN Number of regions where z direction net thickness (DZN)
is changed.
IDCODE = 0 means do not print the modified distributions;
= 1 means print the modified distributions.
