Pollutant Source - [source code]
Define a pollutant emission source for the wind study: a closed volume (stack tip, traffic corridor box, exhaust vent) releasing a named species at a mass rate. Wire into the Eddy3D Case component's Sources input; the species is transported as a passive scalar with turbulent diffusivity (Sct) on every direction case, and the concentration field (kg/m3) is read back by probing the species name.
Input
| Name | Nickname | Description | Type |
|---|---|---|---|
| Geometry | Geo | Closed mesh of the emitting volume, in metres. Thinner than the local mesh cells selects no cells — thicken it or refine around it. | Mesh |
| Species | Field name of the emitted species — pick a common one from the dropdown or type any OpenFOAM word. Sources sharing a name solve as ONE concentration field; distinct names each add a transport solve per iteration. | Text | |
| Rate | kg/s | Total emission of this source in kg/s. The transport is linear, so results rescale to any other rate without re-running. | Number |
| Schmidt | Sct | Turbulent Schmidt number of the species (default 0.7, standard for atmospheric dispersion). Lower spreads the plume faster. | Number |
Output
