`GRIDFILE`

Recognised by the OPM Flow parserGRID

This keyword controls the output of a standard GRID or extended GRID file, as well as the extensible EGRID file for post-processing applications. The extended and extensible GRID formats are comparable; however, the extensible GRID format is more compact and is the only format supported by OPM Flow.

Notes:

The keyword is terminated by a “/”.

Records: Fixed number of records
Record count: 1
Items per record: 2

Parameters

No.	Name	Description	Type	Default
1	`GRID` manual: `NGRID`	A positive integer that controls the output of the GRID geometry file: - for no GRID file to be written out. - for the standard GRID file to be written out. - for the extended GRID file to be written out. Only the default value of zero is supported.	INT	0

Example
