有偿请教剖分问题本人的课题是研究电抗器损耗。其结构如下图：绕组部份由十五层并联而成，每层绕组厚度为3mm.层与层的间隙为0.5mm。绕组上下是铝质结构件。最后给空气建模，建成半径为1m的大球。由于尺寸相差太大，不好剖分。请教如何剖分。

没有明白你说的意思。

xianzhang · 发表于 2009-3-11 20:12

我的意思就是：按上面的命令建完的模型怎么剖分

16443 · 发表于 2009-3-12 08:29

你想要剖分成怎样的？

venture · 发表于 2009-3-12 08:31

最大尺寸和最小尺寸相差2000倍，如果不对模型进行简化处理，就是勉强给你画出来，计算精度和计算时间都无法保证。

xianzhang · 发表于 2009-3-12 09:36

最大尺寸和最小尺寸相差是相差很大.但是我觉得模型简化后不能很好反应真实情况.我导师又要我做一个完整模型的.所以现在愁啊

我只要剖分后能算就行
