Abstract
In this paper, we present a discontinuous Galerkin solver based on previous work by the authors for magnetohydrodynamics in form of a new fluid solver module integrated into the established and well-known multiphysics simulation code flash. Our goal is to enable future research on the capabilities and potential advantages of discontinuous Galerkin methods for complex multiphysics simulations in astrophysical settings. We give specific details and adjustments of our implementation within the flash framework and present extensive validations and test cases, specifically its interaction with several other physics modules such as (self-)gravity and radiative transfer. We conclude that the new DG solver module in flash is ready for use in astrophysics simulations and thus ready for assessments and investigations.
