Question

ABAQUS 从Standard到Explicit数据传递 请教

用STANDARD的三维应力单元模拟得到在均一恒定温度场下材料的变形和热应力后，想将该结果作为预定义场导入DYNAMIC-EXPLICIT继续分析模型在冲击载荷下的响应，出现报错：说导入的原始模型必须是耦合温度单元。难道三维应力单元的状态就不能导入吗？虚心求教大家，谢谢~~~

***ERROR: *INITIAL CONDITIONS,TYPE=TEMPERATURE OR *INITIAL CONDITIONS,
TYPE=FIELD WAS USED IN THE PREVIOUSANALYSIS. TEMPERATURE AND FIELD VARIABLES ARE CURRENTLY NOTTRANSFERRED WHEN ELEMENTS OTHER THAN COUPLEDTEMPERATURE-DISPLACEMENT ELEMENTS ARE IMPORTED. THE IMPORT ANALYSIS WILL NOT BE CONTINUED.

Answer 1

Specification of initial conditions for temperatures and field variables is not allowed in an import analysis, unless all the elements being imported are coupled temperature-displacement elements.--ABAQUS manual scripts.

对于含有温度场的import分析，前一分析中的单元类型必须使用coupled temperature-displacement elements

Answer 2

单元形式都不一样当然不能了啊，热分析时再选单元

追问

都是三维应力单元啊
只不过原始分析是静态隐式算法，后续分析是动态显示算法
