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" N. Z; M1 K0 B# h, o4 ~
问题是这样的：
5 N' m% G; p/ H, F. X# e0 |1 z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。 O* G# ?% ]3 W' I
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
