ABAQUS中，同一个模型，为什么设置使用多个处理器并行计算时就出错了？

设置两个处理器并行计算后出现错误这个The deformable element nodes contained in node set ErrNodeRotNodeNoRotInert-Step1 have no rotary inertia associated with them and some rotational degrees of freedom at the nodes are not constrained. Either rotary inertia must be defined or all of the rotational degrees of freedom must be constrained. See the status file for further details.

如果不使用多个处理器并行计算就可以运算
