“…The computational code, generated by the Simflowny platform [65][66][67][68], runs under the SAMRAI infrastructure [69][70][71], which provides parallelization and the adaptive mesh refinement required to resolve the different scales in the problem. We use fourth-order spatial, finite difference operators to discretize the EKG equations, which are evolved in time using a fourth-order Runge-Kutta integrator [72].…”

“…The publicly available code MHDuet is generated by the open-source platform SIMFLOWNY [45][46][47] to run under the SAMRAI infrastructure [48,49], which provides parallelization and adaptive mesh refinement. The code has been extensively tested for different scenarios [22,[28][29][30], including basic tests of MHD and general relativity (GR) with several numerical schemes.…”

Neutron star mergers are very violent events involving extreme physical processes: dynamic, strong-field gravity; large magnetic field; very hot, dense matter; and the copious production of neutrinos. Accurate modeling of such a system and its associated multimessenger signals, such as gravitational waves, short gamma ray bursts, and kilonova, requires the inclusion of all these processes and is increasingly important in light of advancements in multimessenger astronomy generally, and in gravitational wave astronomy in particular (such as the development of third-generation detectors). Several general relativistic codes have been incorporating some of these elements with different levels of realism. Here, we extend our code MHDuet, which can perform large eddy simulations of magnetohydrodynamics to help capture the magnetic field amplification during the merger, and to allow for realistic equations of state and neutrino cooling via a leakage scheme. We perform several tests involving isolated and binary neutron stars demonstrating the accuracy of the code.
