When I mesh with tet, for the same number of nodes, the run times for the tet are significantly greater than those for the hex. It seems that it takes much longer for the tet mesh's solution to converge (a lot more iterations). Why? I am assuming that the matrix size is the same...
解决的最好办法要么就自由网格划分，要么就用布尔运算里分割命令实现六面体网格划分
解析 Tet-Free划分的网格为自由网格,局限性小 ,任何情况都可以用,划分的网格形状为三角形,精度可能会稍低,不过能满足大部分的要求.Hex-Mapped为映射网格划分,有时候有局限性可能生成不了映射网格,但网格的划分为六边形,可以用尺寸加以控制.Hex-Sweep为能过扫描的方式划分网格. ...
