| Class | |
| Foam::zoneGenerators::Union | |
| Description | |
| A zoneGenerator which selects all the elements from the zones generated by | |
| the given list of zoneGenerators | |
| A union of faceZones is oriented only if ALL the faceZones combined are | |
| oriented, otherwise the returned faceZone is unoriented. | |
| Usage | |
| \table | |
| Property | Description | Required | Default value | |
| type | Type: union | yes | | |
| name | Name of the zone | no | zoneGenerator name | |
| zoneType | Type of zone | no | all the zone types | |
| moveUpdate | Switch to update after mesh motion | no | false | |
| \endtable | |
| These options are followed by a list of any number of zoneGenerators | |
| which can either generate the zones locally or return zones from the lists | |
| of zones held by the mesh using the zoneGenerators::lookup zoneGenerator. | |
| Each zoneGenerator returns a zoneSet containing a pointZone and/or a | |
| cellZone and/or a faceZone, the zoneGenerators::Union operation combines | |
| each of the zone types unless the \c zoneType is specified in which case | |
| only the zones of that type are combined. | |
| A cellZone named \c coneAndAnnulus containing the cells with centres | |
| inside the union of the predefined \c cone1 cellZone which is looked-up | |
| from the cellZoneList and the locally defined annulus is be generated by | |
| \verbatim | |
| coneAndAnnulus | |
| { | |
| type union; | |
| cone1; | |
| annulus1 | |
| { | |
| type annulus; | |
| zoneType cell; | |
| point1 (-0.0075 0 -1); | |
| point2 (-0.003 0.0025 1); | |
| outerRadius 0.002; | |
| innerRadius 0.001; | |
| } | |
| } | |
| \endverbatim | |
