High-Accuracy Approximation of High-Rank Derivatives: Isotropic Finite Differences Based on Lattice-Boltzmann Stencils

Figure 1

Order of convergence of the numerical error for some derivative approximations. The lattice-Boltzmann stencil D2V141 has been utilized. The dashed lines indicate 2nd-, 4th-, 6th-, and 8th-order convergence.
