  "abstract": "We present 1D-MESA2HYDRO-3D, an open source, Python-based software tool that provides an accessible means of generating physically motivated initial conditions (ICs) for hydrodynamical simulations from 1-D stellar structure models. We test 1D-MESA2HYDRO-3D on five stellar models generated with the MESA stellar evolution code and verify its capacity as an IC generator with the Phantom smoothed-particle hydrodynamics code \\citep{MESAIV, Phantom}. Consistency between the input density profiles, the 1D-MESA2HYDRO-3D-rendered particle distributions, and the state of the distributions after evolution over $10$ dynamical timescales is found for model stars ranging in structure and density from a radially extended supergiant to a white dwarf.",
