| Class | |
| Foam::fvCellZone | |
| Description | |
| cellZone selection or generation class with caching of zone volume | |
| for fvModels, fvConstraints, functionObjects etc. | |
| The cellZone is either looked-up from the mesh or generated by a | |
| zoneGenerator and stored locally. | |
| Usage | |
| Examples: | |
| \verbatim | |
| // Select all cells | |
| cellZone all; | |
| // Select the cells within the given cellZone | |
| cellZone rotor; | |
| // Select the cells within the given box | |
| cellZone | |
| { | |
| type box; | |
| box (3.48 -0.1 -0.1) (3.5 0.1 0.1); | |
| } | |
| // Select the cell containing the given point | |
| // and update the cells with respect to the fixed points | |
| // if the mesh moves | |
| cellZone | |
| { | |
| type containsPoints; | |
| moveUpdate true; | |
| points ((0.075 0.2 0.05)); | |
| } | |
| \endverbatim | |
