Description
This overview talk will summarize the status of the numerical modelling of neutron-star mergers. The focus will be particularly on the role of neutrinos, which determine the composition of matter ejected during and after the neutron-star collision and thus the properties of the electromagnetic kilonova emission. A newly developed, computationally fast 'Improved Leakage-Equilibration-Absorption Scheme' (ILEAS) will be introduced. This new treatment allows for efficient simulations of large model grids, which is necessary to explore the high-dimensional space of merger parameters and conditions.
