AB: In a recent paper, MacNeice et al (Ap.J. v614) presented the first complete MHD simulation of the `Breakout' model for CME initation. They used an idealized magnetic topology in 2.5D, with an initial symmetry plane at the equator. We have modified this configuration to test the breakout model in an initial topology without this symmetry. We examine the differences in the two simulations, experiment with applying the driving shear to the different flux systems in this complex configuration, and study the implications for the evolution of magnetic helicity.
