Right now I am simulating pollution dispersion in an urban canyon. I having some problems when i run it in fluent. Attach here is the pic of the urban canyon i am trying to solve. What i want to do is to disperse a co2 source at the center of the bottom of the pic. I have tried doing species transport but there is no coordinate to refer to for my dispersion. How can I solve this in fluent. Many thanks in advance.

what are the symmetry planes doing inside the computational domain? periodic bc are mentioned ok..do the symmetry planes belong there?
The geometry you have is simply a nice 3D backward and forward facing step profile..should be easily to track co2 particles here..
You do not need species transport..rather do a scalar transport modeling ..its straightforward using Fluent's manual.
Just to make sure you get good flow convergence - try running the problem with no scalars (co2 fraction) and compare with some literature data for 3D flow over these step like boundaries.
