Divergence-free magnetohydrodynamics on conformally moving, adaptive meshes using a vector potential method

We present a new method for evolving the equations of magnetohydrodynamics (both Newtonian and relativistic) that is capable of maintaining a divergence-free magnetic field (∇⋅B=0) on adaptively refined, conformally moving meshes. The method relies on evolving the magnetic vector potential and then...
