NMATRIX

Recognised by the OPM Flow parserRUNSPEC

The NMATRIX keyword activates the Discretized Matrix Dual Porosity option and specifies the number of sub-grid blocks in the actual matrix grid blocks. See also the NMATOPS keyword in the GRID section that defines various parameters for this option.

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 “/”.

Note the keyword cannot be used in conjunction with the TRPLPORO keyword, which is also in the RUNSPEC section.
