Description
I will discuss progress and challenges in the numerical simulation of accretion disks, with a focus on applications to protoplanetary disks and planet formation. Starting from the hydrodynamic and MHD simulations that were already feasible in the 1990s, algorithmic and hardware progress has allowed the inclusion of non-ideal MHD processes, dust physics, and radiation, helping to establish and inform the current paradigm of wind-driven protoplanetary disks that support weak turbulence. I will describe recent simulation work that connects to observations of circumplanetary disks, and to Solar System cosmochemical inferences, and preview CCA work to develop next generation simulation tools.
