Feedback processes associated with active galactic nuclei (AGN) found at the centers of clusters of galaxies are a possible source for weak cluster-wide magnetic fields. However, the scales and physics involved in studying these processes necessitate the use of subgrid techniques. We present large-scale simulations of clusters using the 3D adaptive mesh refinement MHD solver in FLASH. We couple this solver to a subgrid model of the accretion onto AGN and the subsequent injection of kinetic, thermal, and magnetic energy. We employ a newly-developed fast and highly parallel halo finder to track the evolution of AGN in a cosmological volume. We study a variety of plausible subgrid models and discuss their impact on accretion rates and cluster magnetic properties.
