初學ansys，各種不懂。想做一個空間桁架受力分析，然后代碼寫了，導入ansys后加載，實常數，單元類型，材料屬性都定義了，就是不求解，也查不到錯，求大神們指教T^T
/ X, f L5 z" l1 V6 g+ }; c問題是這樣的：
8 F/ Q7 M' W; P線L1，L9受Y負方向的均布載荷1000N/m，關鍵點7,15,19全約束，受重力場的影響下看它的變形和應力。
$ S! A: J6 l9 V! d這個是我寫的APDL代碼

究竟是ansys14的BEAM單元的問題還是我自己的問題，反正我就是不能用梁單元在ansys里求解。用solid95單元的話，這個結構分網困難，難以計算，簡化就不求解，求給位大神指點，小弟感激不盡T^T4 u) l' Y- _+ W: ~; I
