Understanding the formation and evolution of cosmological structure is one of the most pressing challenges in modern astrophysics. The last decade has seen a rapid improvement in our ability to observe galaxies, galaxy clusters, and the cosmic web a change that requires corresponding gains in our ability to model these structures in order to understand them. In this talk, I will discuss my efforts to understand cosmological structure formation using large-scale numerical simulations. I will explain the fundamental methods used to model these systems, and will show recent results from simulations of galaxy clusters in particular, results that include sophisticated physical treatments of the intracluster medium and of gravitational lensing.
