Asking for help in studies

my task is to simulate the distribution of contamnate concentrations in a room with a pollutant source from the room surfaces (walls, floor and ceiling) can anyone tell me how to add the pollution in the model, how to set values? thank u!

You could probably use a multispecies model, if you have a way to get the diffusion coefficient.

If it's traces of contaminant, just inject particles using the DPM model.

thank you very much for reply,
Yes, I have the diffusion coefficient of gas. I don't know where I find multi species, help me please.

thank you very much for reply,
I introduce the gas, but in boundary conditions I found the Mass fraction, but in our work, I need to introduce a flow from the chamber walls.
