What role does UV opacity play in the structure and evolution of accretion disks? What can simulations tell us about how winds are launched by radiation and, in particular, how that launching feeds back on the disk structure? Given the limits of numerical simulations, how can we best design the simulations that address these issues? Do the outflows being launched at relatively small radii in accretion disk simulations connect with either the broad absorption line quasars or ultrafast outflows?
