`MULTIPLY`

Recognised by the OPM Flow parserGRIDEDITPROPSREGIONSSOLUTION

Variant 1 — GRID section

The MULTIPLY keyword multiplies a specified array or part of an array by a constant. The constant can be an integer or real value depending on the array type; however, the arrays that can be operated on are dependent on which section the MULTIPLY keyword is being applied in.

Notes:

Where NX, NY and NZ are the dimensions of the model as defined on the DIMENS keyword in the RUNSPEC section.

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

Examples of the arrays most commonly operated on in each section are given in Table 6.69. Cells colored red indicate arrays that are not supported by OPM Flow operations.

Variant 2 — EDIT section

The MULTIPLY keyword multiplies a specified array or part of an array by a constant. The constant can be real or integer depending on the array type; however, the arrays that can be operated on is dependent on which section the keyword is being used.
