AGN Heating of Cooling Flow Clusters: Problems with 3D Hydrodynamic   Models
  We have performed a set of high resolution, three dimensional simulations of a jetted AGN embedded in a relaxed cooling cluster. To the best of our knowledge, these are the first simulation to include both full jet dynamics and a feedback model. These ideal hydrodynamic simulations show that, although there is enough energy present to offset cooling on average, the jet heating is not spatially deposited in a way that can prevent catastrophic cooling of the cluster.
