關于ansys14.5空間桁架梁計算求助

懶趴趴的熊

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(shù)，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
# z" M5 t/ x+ h! b3 _' a" j問題是這樣的：
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。
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(wǎng)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^T

沒有人頂貼幫忙嘛T^T

前處理弄完了就繼續(xù)設定邊界條件啊

你最好把命令流貼出來，給你看看。
