请教abaqus errors!
这是做的一个热传导的例子,在分析时出错,提示:1600 elements have been defined with zero hour glass stiffness. You may use *hourglass stiffness or change the element type. The elements have been identified in element set ErrElemZeroHourGlassStiffness.
3949 elements are missing elastic property reference. The elements have been identified in element set ErrElemMissingElasticPropRef.
A heat transfer analysis is not meaningful since there are no temperature degrees of freedom in the model
Only degrees of freedom 11 and above can be active in the model for this procedure. Check the procedure and element types used in this model.
Invalid load type on element 1275 instance part-1 ptfe-1. Load type f is not valid for element type c3d8
...........
Invalid load type on element 1320 instance part-1 ptfe-1. Load type f is not valid for element type c3d8
请问这些是什么问题?该怎样解决?
谢谢! 英文写的很清楚了,自己查字典看看
就是第一条可能不太好解决,一般不太可能是沙漏的问题,除非出现在initional step中。看看刚度吧 就是第一条解决了(设置单元时不要用缩减积分就行了)
英文我也看得懂 但是为什么会出现,怎么解决,还不知道,所以才问大家的 第二条说要设置材料的弹性特性,对于这一点我很奇怪,非耦合热传导不是只设热导率就行了吗?
第三条说没有温度自由度,就更奇怪了,我在边界条件设了温度了啊。
希望大家给予诚恳的帮助! 第二条 你可以看到的单元有位移自由度的,需要考虑热涨率和刚度
第三条 单元类型dc3d8
