DM halo shapes are determined using an iterative method based on the inertia tensor for a wide range of $z=0$ masses ($M_{200} = 1 \\times 10^{11} - 3 \\times 10^{14} M_\\odot$). Convergence tests shows that the local DM shape profiles are converged only for $r > 9\\epsilon$, $\\epsilon$ being the Plummer-equivalent softening length, larger than expected.
