We present the results of numerical simulations of nonlinear gravitational clustering in universe dominated by weakly interacting, ''cold'' dark matter (e.g., axions or photinos). These studies employ a high resolution N-body code with periodic boundary conditions and 32,768 particles; they can accurately represent the theoretical initial conditions over a factor of 16 in length scale. We have followed the evolution of ensembles of models with ..cap omega.. = 1 and ..cap omega.. < 1 from the initial conditions predicted for a ''constant curvature'' primordial fluctuation spectrum.
