my task is to simulate contamnate concentration in a room with a pollutant source in the center without any chemical reaction. can anyone tell me how to add the pollution in the model, how to set values? thank u!

A way to do it is to include a scalar equation that will represent the contaminant. See the manual to do that. Values of the initial and boundary conditions as well as diffusivities will depend on the kind of model you will use, laminar or turbulent.

Hope this help

newbie

i will try. thanks!
