PLMIXNUM
Recognised by the OPM Flow parserREGIONS
The PLMIXNUM keyword defines the polymer region number for each grid block that is used to assign the mixing tables as well as the maximum polymer and salt concentrations, as defined by the PLMIXPAR and PLYMAX keywords in the PROPS section, for when the polymer option has been activated by the POLYMER keyword in the RUNSPEC section.
The maximum polymer concentration and the associated salt concentration are declared on the PLYMAX keyword.
Notes:
The number of entries should correspond to the NX x NY x NZ parameters on the DIMENS keyword in the RUNSPEC section, unless the BOX keyword defines a sub area of the grid, in which case the total number of entries should correspond to the number of cells defined by the BOX statement.
If a cell is not assigned a PLMIXNUM region then the default value of one will be used.
The keyword is terminated by a “/”.
See also the PLYADS, PLYADSS, PLYDHLF, PLYMAX, PLYROCK, PLYSHEAR, PLYSHLOG and PLYVISC keywords in the PROPS section.

Parameters
| No. | Name | Description | Default |
|---|---|---|---|
| 1 | PLMIXNUM | PLMIXNUM defines an array of positive integers greater than or equal to one, that assign a grid cell to a particular table of mixing parameters as defined by the PLMIXPAR and PLYMAX keywords. The maximum number of PLMIXNUM regions is set by the NPLMIX variable on the REGDIMS keyword in the RUNSPEC section. | 1 |
Example
The example below sets three PLMIXNUM regions in the model on a layer by layer basis, using the EQUALS keyword.

-- ARRAY CONSTANT ---------- BOX ---------
-- I1 I2 J1 J2 K1 K2
EQUALS
PLMIXNUM 1 1* 1* 1* 1* 1 12 / SET REGION 1
PLMIXNUM 2 1* 1* 1* 1* 13 55 / SET REGION 2
PLMIXNUM 3 1* 1* 1* 1* 56 120 / SET REGION 3
