      abstract     = {PUNCH4NFDI is the consortium of particle and astroparticle
                      physics, astrophysics, and hadronic and nuclear physics in
                      the NFDI (national research data infrastructure), Germany.
                      It aims at developing concepts and tools for efficient
                      management of digital research products in fundamental
                      physics and promotes the idea of FAIR data - which is to
                      make scientific data sets findable, accessible,
                      interoperable, and reusable. Here we concentrate on the aims
                      and measures of PUNCH4NFDI in the context of astrophysics
                      simulations. As a first step towards better understanding
                      the software usage of the astrophysics simulation community
                      in Germany, PUNCH4NFDI developed a 14-question survey. We
                      distributed the survey through various channels (mailing
                      list, conference flyer, personal communication) in 2022. In
                      total, 130 computational astrophysicists responded to our
                      survey. We found that predominantly codes able to simulate
                      gravitational N-body problems and magnetohydrodynamics are
                      used by the German astrophysics community. Computer programs
                      typically associated with research in solar physics and
                      numerical relativity turned out to be applied to a lesser
                      degree. The degree to which the FAIR principles are already
                      applied varies greatly. In many cases a basic software
                      version is open access, however, the newest work is often
                      based on modified and unreleased versions. The degree of
                      practising the FAIR principles is often a question of
                      available manpower. Some codes are developed and used by
                      single local research groups, others by large research
                      consortia spread around the globe. While smaller research
                      groups are in principle willing to publish and openly share
                      their simulation data, they often simply lack the manpower
                      to do so. We also found that most astrophysicists in Germany
                      view re-using other researchers' data sets as highly
                      desirable.},
