Abaqus -如何应用初始条件作为塑性应变？

Question

我正在尝试申请在Abaqus中应用塑料应变初始条件，如下所示：

** ----------------------------------------------------------------
*Initial Conditions, type=PLASTIC STRAIN 
test_elements, 0.338, -0.276, -0.0618, 0.0447
**
** STEP: Step-1

代码的这一部分可以在有压力的情况下工作，但不能用于塑料应变。计算没有出现错误，abaqus运行，但当我检查结果时，它没有考虑我的塑性应变…

Answer 1

那么让它运行的唯一问题是test_elements上的额外引号集吗？不确定剩下的问题是什么？
