關(guān)于ansys14.5的空間桁架

懶趴趴的熊

初學(xué)ansys,，各種不懂,。想做一個(gè)空間桁架受力分析,，然后代碼寫了,，導(dǎo)入ansys后加載，實(shí)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(cuò),，求大神們指教T^T
. U8 I: ]& G% F6 [: P* ^4 W問題是這樣的：
線L1，L9受Y負(fù)方向的均布載荷1000N/m,，關(guān)鍵點(diǎn)7,15,19全約束,，受重力場(chǎng)的影響下看它的變形和應(yīng)力。
這個(gè)是我寫的APDL代碼

  h9 o5 e' i. c+ d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?jiǎn)卧�在ansys里求解,。用solid95單元的話，這個(gè)結(jié)構(gòu)分網(wǎng)困難,，難以計(jì)算,，簡(jiǎn)化就不求解，求給位大神指點(diǎn),，小弟感激不盡T^T
