Graphical analysis of the heating and cooling terms from Figure 10 at selected heights. Histograms and pie charts represent the contributions of the heating and cooling terms in the internal energy equation at z = 10, 6, 3, 1, 0, −1 Mm. The left column of plots corresponds to the simulation with a vertical magnetic field, and the right column to the simulation with an arcade-like magnetic field. Each histogram is accompanied by two pie charts illustrating the relative contributions of the individual terms to the total heating and cooling.
