TRANGL

Recognised by the OPM Flow parserGRID

TRANGL enables Non-Neighbor Connections (“NNC”) between the global cells and the Local Grid Refinement (“LGR”) cells to be manually specified, as opposed to the simulator calculating the transmissibilities. The LGR keyword in the RUNSPEC section should be utilized to define the presence of LGRs in the model and to define various LGR dimension parameters.

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

Notes:

Each record must be terminated by a “/” and the keyword is terminated by a “/”.

Parameters

No.NameDescriptionTypeDimensionFieldMetricLabDefault
1IL
manual: I1
A positive integer that defines the LGR grid block in the I-direction in a non-neighbor connection, must be greater than or equal to one and less than or equal to NX on the CARFIN keyword in the GRID section.INTNone
2JL
manual: J1
A positive integer that defines the LGR grid block in the J-direction in a non-neighbor connection, must be greater than or equal to one and less than or equal to NY on the CARFIN keyword in the GRID section.INTNone
3KL
manual: K1
A positive integer that defines the LGR grid block in the K-direction in a non-neighbor connection, must be greater than or equal to one and less than or equal to NZ on the CARFIN keyword in the GRID section.INTNone
4IG
manual: I2
A positive integer that defines the GLOBAL grid block in the I-direction in a non-neighbor connection, must be greater than or equal to one and less than or equal to NX on the DIMENS keyword in the RUNSPEC section.INTNone
5JG
manual: J2
A positive integer that defines the GLOBAL grid block in the J-direction in a non-neighbor connection, must be greater than or equal to one and less than or equal to NY on the DIMENS keyword in the RUNSPEC section.INTNone
6KG
manual: K2
A positive integer that defines the GLOBAL grid block in the K-direction in a non-neighbor connection, must be greater than or equal to one and less than or equal to NZ on the DIMENS keyword in the RUNSPEC section.INTNone
7TRAN
manual: TRANSNNC
TRANSNNC is a positive real number greater than or equal to zero that defines the transmissibility between the GLOBAL grid block (I1, J1, K1) and the LGR grid block (I2, J2, K2). The default value of zero sets the transmissibility between the two cells to zero.DOUBLETransmissibilitycP.rb/day/psiacP.rm3/day/barscP.rcc/hr/atm0.0

The above example defines the transmissibility between LGR cell (1, 1, 1) and global cell (1, 1, 2), LGR cell (1, 1, 2) and global cell (1, 1, 3) and finally between LGR cell (1, 1, 3) and global cell (1, 1, 4) to be 0.2500.
