初學(xué)ansys,各種不懂。想做一個空間桁架受力分析,然后代碼寫了,導(dǎo)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^T4 P7 L1 e5 j: _. b* N4 R4 }9 A2 [
問題是這樣的:
: R) f9 l% Z8 r% J1 Y線L1,L9受Y負(fù)方向的均布載荷1000N/m,關(guān)鍵點7,15,19全約束,受重力場的影響下看它的變形和應(yīng)力。

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(jié)構(gòu)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
