Description : All of these simulations have been performed in full general relativity using the fourth-order finite-differencing code McLachlan. At the same time, the general-relativistic hydrodynamics equations have been solved using the finite-volume code Whisky, where “hybrid equations of states (EOSs)” combined with an ideal-fluid and a piece-wise polytropes EOS for APR4, ALF2, SLy, H4 or GNH3 have been used.
