DISPERC
Recognised by the OPM Flow parserGRID
The DISPERC keyword defines the mechanical dispersivity for all cells in the model via an array.
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.
The keyword is terminated by a “/”.
Note
The option has been tested in combination with the CO2STORE, H2STORE, BIOFILM, or MICP keywords, but not for the general case at this point.
See also the CO2STORE and H2STORE keywords in the RUNSPEC section that active OPM Flow’s CO2 and H2 storage models respectively.

Parameters
| No. | Name | Description | Field | Metric | Lab | Default |
|---|---|---|---|---|---|---|
| 1 | DISPERC | DISPERC is an array of real positive values that defines the mechanical dispersivity for each cell in the model. Repeat counts may be used, for example 20*1.0. | feet | m | cm | None |
Example
The example sets the mechanical dispersivity for all cells in the model to 1.0.
