We describe numerical simulations of large-scale structure formation from cosmic strings and massive neutrinos. The linear power spectrum in this model resembles the cold-dark-matter power spectrum. Galaxy formation begins early, and the final distribution consists of isolated density peaks embedded in a smooth background, leading to a natural bias in the distribution of luminous matter. The distribution of clustered matter has a filamentary appearance with large voids and visually resembles the survey done by the Center for Astrophysics.
