摘要：

LB simulations can be affected by the arising of initial layers due to an inconsistent initialization of the discrete LB populations. We present some previously proposed initialization routines built to overcome that problem; using the asymptotic expansion technique, we show how their features can be analyzed and, in some cases, how accuracy and computational efficiency can be improved.
