Abstract
The numerical simulations of binary neutron star mergers is an important, but computationally expensive endeavor. The authors demonstrate that significant computational savings can be realized by adopting a hybrid approach to these simulations by using a fully dynamical spacetime solver initially, but switching to a conformally-flat spacetime solver as the system evolves.
