Density and V-web classification of a gravity-only ΛCDM simulation. The cube is divided into a N_g = 512³ cells grid on which both the density and the eigenvalues of the shear velocity tensor have been calculated, applying a smoothing of R_s = 1 Mpc/h. Panels a and b show the logarithm of the DM density at redshifts 2 and 0 respectively (in a slice that has a thickness of ∼1.5 Mpc/h). Panels c and d contain, for the previous redshifts, the classification into CW elements performed by the V-web method for an λ_th = 0 (in a middle slice that is one grid cell thick). Panels e and f contain the same as the previous two, but for the λ_th = 0.44 proposed by Hoffman et al. (2012).
