The common envelope phase in binary star systems is simulated using the 3-D moving-mesh hydrodynamic code MANGA. The radiation hydrodynamics module in MANGA is modified using a sub-cycling algorithm to skip unnecessary calculations. The sub-cycling as well as other optimizations reduce computation time by a factor of 3. The generation of appropriate initial conditions for radiation hydrodynamic simulations is discussed.Références
