關(guān)于ansys14.5空間桁架梁計(jì)算求助

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(xiě)了,，導(dǎo)入ansys后加載,，實(shí)常數(shù),，單元類(lèi)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
" Q% }2 N2 o& I問(wèn)題是這樣的：
線(xiàn)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,。

前處理弄完了就繼續(xù)設(shè)定邊界條件啊

問(wèn)題是邊界條件設(shè)定完之后就不求解了,，找不出原因,。

你最好把命令流貼出來(lái)，給你看看,。
