An Extension of Gmunu: General-relativistic Resistive Magnetohydrodynamics Based on Staggered-meshed Constrained Transport with Elliptic Cleaning

We present the implementation of general-relativistic resistive magnetohydrodynamics solvers and three divergence-free handling approaches adopted in the G eneral-relativistic mu ltigrid nu merical ( Gmunu ) code. In particular, implicit–explicit Runge–Kutta schemes are used to deal with the stiff t...
