Fig. 1


Effect of different optimisation options in the convergence behaviour. Each panel was calculated using a 5-level Mg ii atom with PRD in the h&k lines, for different columns of a 3D MHD simulation. Top panel: effect of Ng acceleration and PRD switching. Middle panel: effect of grid optimisation. Bottom panel: effect of different starting solutions.
