**********************************************************************
请问：我在做morph的的时候都是将模型的尺寸缩小。。。所以设计变量为负数。可是-1，负的边界，是不是还可以继续优化。。。
（因为morph 无法确定morph多少比较合适）缺乏工程经验。
求详解。。希望共同探讨。。
是不是设计的morph shape 的尺寸太小。。我的设计变量 是不是还有很多余量？？？？ 本帖最后由 417332551 于 2011-7-5 22:52 编辑
优化结果 网格 尺寸0.4 你这么多行，╮(╯▽╰)╭
也不说这是干啥的 -1.0表示形状变化是朝着预定义的shape的反方向变形
达到边界值，表示还有朝着边界方向进一步优化的空间。 本帖最后由 417332551 于 2011-7-6 08:21 编辑
形状优化 分析的out文件
模型已经贴了图片。
还有out文件用红色的注释了。
我分析的结论也出来了。只是不敢确定，征求一下大家伙的意见。 3# kmani 本帖最后由 417332551 于 2011-7-6 08:21 编辑
谢谢！我也觉得 还有优化空间，还有优化的余量。。。。我就是不确定。。。
谢谢你及时回复。。。。让我释然了。。
怎么样把仿真币给你。。哪位朋友能帮我操作一下。。 4# zkong
