We present a three-dimensional numerical ideal magnetohydrodynamics (MHD) model describing the time-dependent expulsion of a CME form the solar corona. The CME is driven by a twisted magnetic flux rope that is anchored at both ends in the photosphere and embedded in a open bipolar magnetic field. We follow the evolution of the CME from the low corona as it makes its way through surrounding magnetic fields anchored to the sun. We explore the dynamics of the expanding flux rope in 3D space to determine significant MHD effects. This model employs a variety of initial state similar to that suggested by Gibson and Low as a means of producing several notable features of CME's such as a coronal cavity and bright core seen in white-light coronagraphs.Our numerical model is in contrast to traditional CME models that incorporate force-free bipolar magnetic fields. The flux rope configuration offers the advantage of greater magnetic free energy to drive the CME and produces plasma outflows that qualitatively match white-light coronagraph observations of CME structure.
