The effect of subclusters on the development of cD galaxies and the cluster environment is investigated through the use of N-body simulations. The cluster simulations are fully self-consistent with each galaxy represented by a distribution of particles, and the gravitational potential of the cluster as a whole arises from the distribution particles alone. All simulations are carried out using a parallelized ``tree'' algorithm (Dubinski 1996). The computer simulations consist of five single-cluster models and five cluster-merger models. The single-cluster models contain 50 galaxies which are represented by N=80,000 particles. The cluster-crash models consist of two 50-galaxy, single-cluster models on a sub-parabolic glancing collision and are represented by N=160,000 particles. Results show that the production of a central dominant galaxy is the natural product of the cluster simulations and the cluster-merger models. In fact the cluster-merger models are more conducive to producing a more massive central dominant galaxy than the single-cluster models even though the cluster-merger models show a lower rate of galaxy merging than the single-cluster models.
