Simulating disk galaxies and interactions in Milgromian dynamics
  Since its publication 1983, Milgromian dynamics (aka MOND) has been very
successful in modeling the gravitational potential of galaxies from baryonic
matter alone. However, the dynamical modeling has long been an unsolved issue.
In particular, the setup of a stable galaxy for Milgromian N-body calculations
has been a major challenge. Here, we show a way to set up disc galaxies in MOND
for calculations in the PHANTOM OF RAMSES (PoR) code by L\"ughausen (2015) and
Teyssier (2002). The method is done by solving the QUMOND Poisson equations
based on a baryonic and a phantom dark matter component. The resulting galaxy
models are stable after a brief settling period for a large mass and size
range. Simulations of single galaxies as well as colliding galaxies are shown.
