In this model, chondrules, CAIs, AOAs, metal grains and related components of meteorites are assumed to have formed in the outflow region of the innermost regions of the solar nebula and then were ejected, via the agency of a bipolar jet flow, to outer regions of the nebula. The research examined whether size sorting of chondrules and metal grains is a natural consequence of this model. To assist in this task, a multiprocessor system was used to undertake Monte Carlo simulations of the early solar nebula. The paths of a statistically significant number of chondrules and metal grains were analysed as they were ejected from the outflow and travelled over or into the solar nebula. The results suggest that size sorting can occur provided that the solar nebula jet flow had a relatively constant flow rate as a function of time.
