ansys高級(jí)且常見(jiàn)的錯(cuò)誤信息
*** WARNING *** CP = 1.529 TIME= 15:02:35
No new reinforcing elements are created with the last EREINF command.
Please verify your model carefully.
這個(gè)仿真在線學(xué)員提出的一個(gè)問(wèn)題,這句是說(shuō)你的設(shè)置問(wèn)題導(dǎo)致纖維加強(qiáng)筋沒(méi)有創(chuàng)建成功哦。仿真在線培訓(xùn)了那么多學(xué)員,這個(gè)問(wèn)題算比較少見(jiàn),但是怎么解決呢?往下看。
*** WARNING *** CP = 1.529 TIME= 15:02:35
Element shape checking is currently inactive. Issue SHPP,ON or
SHPP,WARN to reactivate, if desired.
這個(gè)是說(shuō)元素形狀檢查開(kāi)關(guān)打開(kāi)啦,為啥會(huì)打開(kāi),一般是你的分析在運(yùn)行過(guò)程中出現(xiàn)了非常高狀況,主要是出現(xiàn)超大的移動(dòng)。比如約束不良,原件飛來(lái)飛起,無(wú)法穩(wěn)定。
*** WARNING *** CP = 1.950 TIME= 15:02:35
Material number 3 (used by element 115) should normally have at least
one MP or one TB type command associated with it. Output of energy by
material may not be available.
這個(gè)是系統(tǒng)ansys wb轉(zhuǎn)成apdl后自己的提示,可以不理。
*** ERROR *** CP = 4.992 TIME= 15:02:37
There is at least 1 small equation solver pivot term (e.g., at the UX
degree of freedom of node 215). Please check for an insufficiently

constrained model.

這個(gè)是本文的主題: 至少有一個(gè)方程在求解時(shí)出現(xiàn)問(wèn)題(支點(diǎn)項(xiàng)),請(qǐng)檢查是否約束不足。

所以,所有問(wèn)題都是因?yàn)檫@個(gè)EREINF 名稱創(chuàng)建失敗,導(dǎo)致有些組件沒(méi)有約束,而導(dǎo)致solver pivot term問(wèn)題。解決辦法是檢查你的reinf為啥會(huì)創(chuàng)建失敗了,不過(guò)這又是我們仿真在線老師說(shuō)的:高級(jí)難的問(wèn)題,大家需要查查相關(guān)文檔。
