Abstract

We present a new direct simulation Monte Carlo method for solving the relativistic Boltzmann equation. We solve numerically the two-dimensional Boltzmann equation using this new algorithm. We find that elliptic flow from this transport calculation smoothly converges toward the value from ideal hydrodynamics as the number of collisions per particle increases, as expected on general theoretical grounds but in contrast with previous transport calculations.
