DZ
Recognised by the OPM Flow parserGRID
DZ defines the size of all grid blocks in the Z direction via an array for each cell in a Cartesian Regular Grid model.
Notes:
The number of entries should correspond to the NX x NY x NZ parameters on the DIMENS keyword in the RUNSPEC section, unless the BOX keyword defines a sub area of the grid, in which case the total number of entries should correspond to the number of cells defined by the BOX statement.
The keyword is terminated by a “/”.
See also the DX, DY and TOPS keywords to fully define a Cartesian Regular Grid.

Parameters
| No. | Name | Description | Field | Metric | Lab | Default |
|---|---|---|---|---|---|---|
| 1 | DZ | DZ is an array of real numbers describing the cell size in the Z direction for each cell in the model. Repeat counts may be used, for example 10*100.0. | feet | m | cm | None |
Example
--
-- DEFINE GRID BLOCK Z DIRECTION CELL SIZE (BASED ON NX x NY x NZ = 300)
--
DZ
100*20.0 100*30.0 100*50.0 /
The above example defines the size of the cells in the Z direction based on 300 cells in the model as defined by the DIMENS keyword in the RUNSPEC section.Manual source: parts/chapters/subsections/6.3/DZ.fodt
