`GRAVDRM`

Recognised by the OPM Flow parserRUNSPEC

This keyword switches on the alternative gravity drainage and imbibition modeling between the matrix and the fracture grid blocks in dual porosity and dual permeability runs. Either the GRAVDRM or GRAVDR keywords should be used to activate this standard or alternative type of formulation.

There is no data required for this keyword.

This keyword is not supported by OPM Flow but would change the results if supported so the simulation will be stopped.

Notes:

The keyword is terminated by a “/”.

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

Parameters

No.	Name	Description	Type	Default
1	`ALLOW_RE_INFL` manual: `OPTION1`	A defined character string that sets the matrix flow in and out of the matrix block option, and should be set to one of the following: YES: oil flow is bi-directional, that is oil can flow into and out of the matrix block. NO: oil flow is uni-directional, that is oil can flow out of the matrix block. `YESNO`	STRING	YES

Example

--
-- ACTIVATE ALTERNATIVE GRAVITY DRAINAGE AND IMBIBITION MODEL
--
-- MATRIX
-- OPTION
GRAVDRM
YES /
The above example switches on the alternative gravity drainage and imbibition option for the run and sets oil flow to be bi-directional, that is oil can flow into and out of the matrix block.
