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
