appleyy Guest Posts: n/a	I want to know the steady concentration of a specie after it is injected from chimney into air,I think it isn't possible to define multiple species,but i don't know how to define material and operating condition,especially how to define the diffusivity of that specie,which I think is the most important parameter in diffusion.And from the caculation,I can only know the velocity of the mass instead of the concentration of it,what is the matter,is diffusion equation included in FLUENT? How can I see it? thank you for your help.
