DTHETAV
Recognised by the OPM Flow parserGRID
DTHETAV defines the size of grid blocks in the THETA direction via a vector as opposed to defining the property for each cell for a Radial Grid. The RADIAL or SPIDER keyword in the RUNSPEC should be activated to indicate that radial geometry is being used.
Notes:
The number of entries should correspond to the NY parameter of the DIMENS keyword in the RUNSPEC section.
The keyword is terminated by a “/”.
Note that the SPIDER keyword activates OPM Flow’s radial grid geometry option for the model. This keyword will create a spiderweb-shaped grid based on a corner-point grid using the standard radial grid keywords: INRAD, DRV, DTHETAV, DZ/DZV etc. in the GRID the section. Spider and Radial grids generated by OPM Flow will be displayed the same in OPM ResInsight, as they are both output as Cartesian Irregular Corner-Point Grids. The difference is that the radial model’s pore volumes are adjusted to match the radial geometry pore volumes, whereas the Spider grid volumes are not adjusted.
See also the DRV, DZV and TOPS keywords to fully define a radial or spider grid model.

Parameters
| No. | Name | Description | Field | Metric | Lab | Default |
|---|---|---|---|---|---|---|
| 1 | DTHETAV | DTHETAV is a vector of real numbers describing the cell size for the grid blocks in the THETA direction in a radial grid. Repeat counts may be used, for example 10*100.0. | degrees | degrees | degrees | None |
Example
--
-- DEFINE GRID BLOCK SIZES IN THE THETA DIRECTION (BASED ON NY = 6)
--
DTHETAV
60.0 60.0 60.0 60.0 60.0 60.0 /
The above example defines the size of the cells in the THETA direction based on NY equals six in the DIMENS keyword in the RUNSPEC section.Manual source: parts/chapters/subsections/6.3/DTHETAV.fodt
