Structure functions S_q^v(r) of the velocity field for the MDPL2 mock cube, shown for several orders q (0.5 ≤ q ≤ 2), using 64 × 10⁶ randomly sampled point pairs. Two regimes are visible: (i) a narrow small-scale range below 40 − 50 h⁻¹ Mpc that does not support genuine scaling, and (ii) a second regime spanning nearly one decade in scale. The latter shows multiaffine behaviour with H = ζ_v^MDPL2(1)≈0.11 and ζ_v^MDPL2(2)≈0.16; the condition ζ_v^MDPL2(2) < 2 ζ_v^MDPL2(1) indicates statistically significant intermittency. Solid lines show linear fits with their slopes indicated above each line.
