Energy evolution for the three simulation series. The change in the particles, field, and total kinetic energy (solid lines, 𝒫), and the net energy exchange rate (dashed lines, ℰ), for Series 1 (first row), Series 2 (second row), and Series 3 (third row) runs in Table 1. Same as in Fig. 3, with the horizontal zero line indicating the separation between positive and negative values.
