We discuss our ongoing analysis of the observational properties of Breakout coronal mass ejections. Presented are quantitative analyses of the post-eruption evolution that produces the commonly observed flare-loop arcades at the limb and the spreading flare ribbons at disk center. The simulation dynamics are compared to observational results of long-duration flares. We also present a novel application of the ionic charge freeze-in analyses to the numerical simulation output. This post-processing allows us to 'predict' the heavy ion charge states (O7+/O6+) from the simulation density, temperature, and velocities. Due to limitations in the energy accounting and initial conditions of the MHD simulation, we do not obtain the observed O7+/O6+ values, but we emphasize the potential of this method and show how it can be used to study relative variation in charge state composition throughout the ejecta volume.
