Figure 6.

Errors in u, p, and χ in L ¹, L ², and $L^{\infty }$ norms for the dynamic (γ=0.15) version of the idealized anisotropic shell model of Section 5.1.1. Reference lines with slopes of ‐1 and ‐2 are also shown. The velocity converges at second‐order accuracy in all norms, whereas the pressure converges at second‐order in the L ¹ norm, at first‐order in the $L^{\infty }$ norm, and at order 1.5 in the L ² norm. The displacement converges at essentially second‐order rates in the L ¹ and L ² norms, and at a slightly lower rate in the $L^{\infty }$ norm
