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.

1DZDZ 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.feetmcmNone

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.
