OPM Flow Keyword Reference

GRIDUNIT

Recognised by the OPM Flow parserGRID

The GRIDUNIT keyword defines the units of the grid data. It is usually output by pre-processing software when exporting the grid geometry. The data is not used by OPM Flow intrinsically, but is merely written to the output EGRID file, as specified by the GRIDFILE keyword, for the use of post-processing software like OPM ResInsight.

Notes:

Note the alternative spelling METRES, that is METERS is not recognized.

The keyword is terminated by a “/”.
