ABAQUS不收斂解決辦法
ABAQUS 在計算分析時遇到: Error in job xxx:Too many attempts made for this increment。 首先檢查模型是否沒有足夠的約束,產生了剛體位移。 若模型設置正確,則是因為迭代分析步不收斂導致的。

Too many attempts made for this increments的實例教程
在用abaqus仿真殼體非線性靜力學分析問題時,報錯
Too many attempts made for this increment
The analysis has been terminated due to previous errors. All output requests have been written for the last converged increment.
Abaqus/Standard Analysis exited with an error - Please see the message file for possible error messages if the file exists.
應該如何調試
展開 總結:如果在達到MInimum之前就達到5U 無連技,就報錯誤1:too many attempts made for this increment。如果沒有達到5U 無連技,先觸發了MInimum,就報錯誤2:Time increment required is less than the minimum specified。兩者的本質來說是差不多的,解決思路也差不多,無法解決的原因也差不多

展開 最近看到有許多用abaqus軟件做有限元的朋友碰到這樣一個問題:
Too many attempts made for this increments。
這個錯誤產生的深層次原因在于,abaqus系統在求解非線性微分方程時采用的是迭代求解,當迭代求解次數大于5次(可以設置)或者增量步小于用戶設定的最小增量步(可以設置)時,就意味著迭代求解的失敗,也就是所謂的求解不收斂。這樣一個問題是一個看似青銅,實則王者的問題,很多人都碰到過這樣一個問題,這是做非線性有限元分析不可避免的。很多人在初次碰到該問題時往往茫然不知所措,而導致不收斂的原因有很多,一般對于初學ABAQUS的新手來說解決起來相當棘手,即使對于一些老鳥也需要花費不少的心思去優化模型。作者在做橡膠材料的許多模擬時也經常碰到這個問題,橡膠試件具有材料非線性(超彈性,粘彈性),幾何非線性(大變形),另外往往還有邊界條件的非線性(邊界條件的突變,比如接觸問題)等等,可以說是非線性分析中的戰斗機了。本文將根據個人仿真和解決問題的經驗,給大家提供一些解決思路,但是個人的見識有限,沒辦法窮舉所有的解決方案,對于具體問題還應該具體分析。給出的建議將主要包括以下模塊部分參數的說明:材料、載荷步、相互作用條件、載荷和網格劃分等。

最近看到有許多用abaqus軟件做有限元的朋友碰到這樣一個問題:
Too many attempts made for this increments。
當折減次數超過5次,那么就會出現我們經常遇到的錯誤信息:“ERROR:?TOO?MANY?ATTEMPTS?MADE?FOR?THIS?INCREMENT:?ANALYSIS?TERMINATED?”。造成這樣的問題往往是因為模型的本身有問題,例如存在剛體位移、過約束、接觸或者塑性材料定義不當、網格過于粗糙或過于細化等。
ERROR: TOO MANY ATTEMPTS MADE FOR THIS INCREMENT—ANALYSIS TERMINATED
2.錯誤:為此增加嘗試太多—分析終止
?這只是一條錯誤消息,解釋了為什么Abaqus最終中止。
?請勿修改求解器控件以增加允許的嘗試次數
每增量。
?檢查消息文件中是否有可能導致收斂的警告消息
困難。

數值奇異問題通常意味模型中的自由度缺少約束因而導致剛體位移,在許多接觸問題中,限制剛體位移的唯一約束需要依靠接觸和摩擦關系的建立,如果在載荷施加時接觸關系尚未建立,在未約束的自由度上就有可能產生不確定的剛體位移,從而產生不穩定問題。
