The initial stages of relativistic heavy ion collisions are studied numerically in the framework of a $\mathrm{}(2+1)\mathrm{}$-dimensional classical Yang-Mills theory. We calculate the energy and number densities and momentum spectra of the produced gluons. The model is also applied to noncentral collisions. The numerical results are discussed in the light of RHIC measurements of energy and multiplicity and other theoretical calculations. Some problems of the present approach are pointed out.
