Clusters of galaxies are powerful probes of cosmological parameters and the astrophysical processes pertaining to the formation of galaxies. Cosmological simulations provide anĀ  extremely useful tool with which to understand the structure of these objects. In this talk, I will present some recent highlights from my simulations of clusters, focusing particularly on the structure of the hot, X-ray emitting intracluster medium, the dominant baryonic component in clusters.
