DX
Recognised by the OPM Flow parserGRID
DX defines the size of all grid blocks in the X 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 DY, DZ and TOPS keywords to fully define a Cartesian Regular Grid.

Parameters
| No. | Name | Description | Field | Metric | Lab | Default |
|---|---|---|---|---|---|---|

Example
--
-- DEFINE GRID BLOCK X DIRECTION CELL SIZE (BASED ON NX x NY x NZ = 300)
--
DX
300*1000 /
The above example defines the size of the cells in the X direction based on 300 cells in the model as defined by the DIMENS keyword in the RUNSPEC section.Related keywords
