Vertical component of (a) vorticity, (b) swirling strength, and (c) shear strength, computed in a small portion of the full simulation domain, measuring 0.6  ×  0.6  ×  1.8 Mm³ and encompassing an intergranular region with strong vertical magnetic field (B_z ≳ 500 G). The gray sheet displays the surface of optical depth τ₅₀₀ = 1, while the plasma flow is rendered with green streamlines. These images were produced with the software ParaView (Ahrens et al. 2005).
