| Foam::Lagrangian::volumeInjection | |
| Description | |
| Volume injection model. This injects particles instantaneously within the | |
| volume of a set of cells. Particles are positioned randomly. | |
| Usage | |
| \table | |
| Property | Description | Required? | Default | |
| cellZone | The name of the cell zone | yes | | |
| number | The number to inject | if numberDensity is \ | |
| not specified | | |
| numberDensity | The number to inject per unit \ | |
| volume | if number is not \ | |
| specified | | |
| time | The time at which to inject | no | 0 | |
| \endtable | |
| Example specification: | |
| \verbatim | |
| <LagrangianModelName> | |
| { | |
| type volumeInjection; | |
| cellZone bed; | |
| numberDensity 2 [mm^-3]; | |
| time 0.01; | |
| } | |
| \endverbatim | |
