Solution of the RMHD blast wave at time \(\pmb{t=4.0}\) , obtained with the ADER-DG \(\pmb{\mathbb{P}_{3}\mathbb{P}_{3}}\) scheme supplemented with the a posteriori second order TVD subcell finite volume limiter. Top panels: rest-mass density (left) and thermal pressure (right). Central panels: Lorentz factor (left) and magnetic pressure (right), with magnetic field lines reported. Bottom panels: AMR grid (left) and limiter map (right) with troubled cells marked in red and regular unlimited cells marked in blue.
