We present numerical MHD simulations that demonstrate, for the first time, the breakout model for the initiation of coronal mass ejections in a general 3D magnetic topology. An elongated bipolar active region configuration with a spine and 3D separator fan surface is shown to build up sufficient magnetic free energy and have the necessary complexity to produce a fast eruption of low-lying sheared flux over part of the active region neutral line. We discuss the details of the overlying breakout magnetic reconnec-tion that triggers the unstable, rapid expansion of sheared flux and the classic eruptive flare reconnec-tion which produces a twisted flux rope structure and a > 1000 km/s eruption.
