在用黃永剛子程序huang.for做晶體塑性有限元分析時,提交計算后log文件顯示奇異矩陣,模型的位移邊界條件用一個子模型驅動,相同的模型不使用umat可以計算,只要加上umat就會有奇異矩陣。




版本:Abaqus 2021問題:1、在Abaqus內導入inp文檔,調用原始的umat子程序huang.for后,多核運行成功。





The error is below:Analysis initiated from SIMULIA established productsAbaqus JOB job1Abaqus 3DEXPERIENCE R2018xAbaqus License Manager checked out the following licenses:Abaqus/Explicit
在提交后程序報錯:ERROR in job messaging system: Error in connection to analysisError in job Job-3-copy-copy-copy: Abaqus/Standard Analysis exited with an error - Please see the message file for possible

Error: Abaqus/Standard Analysis exited with an error - Please see the message file for possible error messages if the file exists.

關于slip spin tensor那里,實在看不懂為什么要那么算,有無大神給我講解一下,或者有無資料推薦?
