[求助]用线形成面以及起重机建模问题
1。我想用4条线来围成一个面，可能是画的时候没注意，有些线的端点在同一坐标上，但却不在一个关键点上，因此无法生成面。ansys中有没有命令可以将坐标相同的keypoint合并起来？2。还有一个问题就是我画起重机的模型，筋板是焊在一整块腹板上的，那么在ansys中一定要让这两个面共线么？有没有其它办法把他们约束起来？[此贴子已经被aspen于2006-3-30 10:02:09编辑过]
re
merge---- node, keypoint,area,Genearally, the areas are naturally jointed together in ansys if without ant specifications
第一问题解决了，谢谢
第二个问题还是不理解，比如这样有两个垂直的面：├，建模时只是生成了两个“看上去”在一起的面，难道ansys会自动把他们连接起来么？
有谁有起重机的模型？能不能给一个参考一下？或是带筋板的箱形梁模型也行啊
起重机模型自己画吧
SW,SE,UG,Pro/E什么软件都行
可以通过布尔运算OVERLAP将它们搭接在一起，这样不但是一个整体，只是有一个共同的边界区域，并且划分单元时还好处理。这样就可以很好的约束了。不知道对不对，我也是没学多长时间，大家一块学习啊！ 龙门起重机的模型

不过看了下help，好像glue比较适合我的意思
还有就是partition似乎也行，不知道partition和glue有什么区别
glue是相同图元（面与面）在公共边界结合，便于网格与应力的连续性，
partition是执行分割命令，便于把网格划分，可以达到你需要的精度。
