Solution of the Leblanc shock tube problem at time \(\pmb{t=6.0}\) , obtained with the ADER-DG \(\pmb{\mathbb{P}_{9}\mathbb{P}_{9}}\) scheme supplemented with the a posteriori second order TVD subcell finite volume limiter. Top left: Troubled cells highlighted in red and unlimited cells in blue. Top right to bottom right: Comparison with the exact solution using a 1D cut through the 2D solution on 200 equidistant sample points for density, velocity and internal energy.
