Description
Magnetic reconnection is an important phenomenon in the astrophysical plasma, e.g. in solar flares, interstellar medium, stellar evolution and supernovae, accretion discs, and jets. We study magnetic reconnection and plasmoid formation in the Orszag-Tang problem. We show magnetic energy reduction caused by magnetic reconnection. We also study the effect of resistivity and compare the numerical resistivity in 2D and 3D magnetohydrodynamics simulations. We also compare Newtonian code (PLUTO 4.4) and general relativistic code (KORAL) performance in this standard test problem.
