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.

1DXDX is an array of real numbers describing the cell size in the X direction for each cell in the model. Repeat counts may be used, for example 10*100.0.feetmcmNone

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.
