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
8 ]( s" k! J1 Q# l问题是这样的：1 D" q5 k5 |4 M/ p
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。" k! x/ S" G9 d; m
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^T3 O A% D8 O2 J$ z7 }2 F* `
