关于ansys14.5空间桁架梁计算求助
初学ansys,各种不懂。想做一个空间桁架受力分析,然后代码写了,导入ansys后加载,实常数,单元类型,材料属性都定义了,就是不求解,也查不到错,求大神们指教T^T问题是这样的:
线L1,L9受Y负方向的均布载荷1000N/m,关键点7,15,19全约束,受重力场的影响下看它的变形和应力。
这个是我写的APDL代码

究竟是ansys14的BEAM单元的问题还是我自己的问题,反正我就是不能用梁单元在ansys里求解。用solid95单元的话,这个结构分网困难,难以计算,简化就不求解,求给位大神指点,小弟感激不尽T^T
在线急等
没有人顶贴帮忙嘛T^T 前处理弄完了就继续设定边界条件啊 eddyzhang 发表于 2014-3-6 20:57 static/image/common/back.gif
前处理弄完了就继续设定边界条件啊
问题是边界条件设定完之后就不求解了,找不出原因。
你最好把命令流贴出来,给你看看。 beam188,189
