The large-scale impact of anisotropic outflows from AGN on metal enrichment of the IGM are investigated by performing N-body simulations of ΛCDM Universe. On Mpc-scales energetic AGN outflows are expected to move away from the high-density regions of large-scale structures. We implement semi-analytical prescriptions of such anisotropic AGN outflows within a cosmological volume. The observed quasar luminosity function is used to get the redshift and luminosity distribution of AGNs, and analytical models are used for the outflow expansion. We compute the fractional volume of the simulation box enriched by the anisotropic outflows of a cosmological population of AGN over the Hubble time, and the metalicity distribution.
