摘要
多重网格方法（ＭＧＭ）具有较快的收敛速度．本文讨论了全近似完全的多重网格方法（ＦＡＳ－ＦＭＧ）在三维室内气流数值模拟中的应用．通过对计算实例的结果分析，表明它的收敛速度比单层网格迭代法提高了３～４倍，并明显地改善了收敛过程的稳定性．
ultigrid Method (MGM) is of high convergence rate. This paper discusses the application of FASFMG to the numerical simulation of threedimensional indoor air. The comparisons of engineering example demonstrate that the convergence rate is accelerated by 3~4 times, compared to the single grid system, and also the convergence stability is apparently improved.
