In this paper we discuss the application of a new diagnostic tool for analysis of flame simulations. This methodologogy is based on following specific chemical elements, e.g., carbon or nitrogen, as they move through the system. From this perspective an "atom" is a component of a molecule that is being transported through the simulation domain by advection and diffusion. Reactions cause the atom to shift from one species to another with the subsequent transport of the atom determined by the movement of the new species.
