They have been modeled numerically for more than a decade through multi-dimensional relativistic MHD simulations, relying on axial symmetry until a few years ago while currently using full three-dimensional simulations employing adaptive meshes. Here, we discuss the most recent findings, especially those obtained by our Arcetri group, focusing on the problem of magnetic field dissipation inside the nebula.STAMPAenArticle10.1007/s12210-019-00759-y2-s2.0-85059878602000501308500012https://link.springer.com/article/10.1007/s12210-019-00759-yhttps://ui.adsabs.harvard.edu/abs/2019RLSFN.tmp....1D/abstractFIS/05 - ASTRONOMIA E ASTROFISICA
