Code Value Meaning
>0 Multiply value of y direction permeability by
VALKY.
NOTE: NUMKY records must be read.

6. II, 12, Jl, J2, Kl, K2, VALKZ
Omit this record ifNUMKZ = 0.
11 Coordinate of first region block in I direction.
12 Coordinate of last region block in I direction.
Jl Coordinate of first region block in J direction.
J2 Coordinate of last region block in J direction.
Kl Coordinate of first region block in K direction.
K2 Coordinate of last region block in K direction.

Code Value Meaning
<0 New value of z direction permeability for region
(md).
NUMKZ
>0 Multiply value of z direction permeability by
VALKZ.
NOTE: NUMKZ records must be read.

24.3.3 Modifications to Transmissibilities
It is important to keep in mind the directional convention used in
specifying transmissibility modifications. For example, in gridblock (I, J, K):

TX(I, J, K) refers to flow across the boundary between blocks 1-1 and I,
TY(I, J, K) refers to flow across the boundary between blocks J-l and J, and
TZ(I, J, K) refers to flow across the boundary between blocks K-l and K.
