Abstract
We describe our utilization of HLRS resources in 2019. Chief among this has been important modeling work closely related to the theoretical interpretation of the first-ever image of a black hole. A large library of theoretical model images was built from computationally expensive magnetohydrodynamical simulations of a magnetized fluid around a black hole. This was an international effort and the HLRS contributed to it. Additionally we developed and tested our algorithms further with direct benefits for the funded project. Lastly we describe key development milestones that were achieved that will enable such matter simulations around two orbiting black holes within the same efficient computational framework.
