ADD

Recognised by the OPM Flow parserGRIDEDITPROPSREGIONSSOLUTION

Variant 1 — GRID section

The ADD keyword adds a constant to a specified array or part of an array. 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 ADD 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 6.4. Cells colored red indicate arrays that are not currently supported by OPM Flow operations.
