The results show that in case of same grid density,BFC method can achieve higher precision. Moreover,BFC has the advantages in grid system,CPU time and memory consumption compared with the conventional method based on Cartesian orthogonal grid system.

• 通过对模拟结果进行比较,表明在相同网格密度下,BFC方法可以获得更高的计算精度,并在网格系统、计算时间和内存消耗综合水平上均比传统的基于笛卡尔正交网格的模拟方法优越。
