THE PROBLEM IS TOO LARGE TO RUN WITH Abaqus.

Error in job Job-1: THE PROBLEM IS TOO LARGE TO RUN WITH Abaqus. TYPICALLY THIS IS CAUSED BY THE EXISTENCE OF A VERY LARGE ELEMENT SUCH AS A SUBSTRUCTURE WITH A LARGE NUMBER OF RETAINED DOF, A LARGE CAVITY IN A CAVITY RADIATION PROBLEM, OR SURFACE-BASED COUPLING WITH A LARGE NUMBER OF COUPLING NODES.

记录一个奇怪的报错信息，纠结很久，希望后续走弯路的人避开。

我设置了一个质量点的耦合，很正常的一个设置情况，如下图

耦合的从节点有9万多个，减少到8万多个就可以计算了，

但是很奇怪的是，另外一个计算模型也是在9万多个从节点，计算没有报错信息，

于是8万多个节点的耦合是删掉部分节点且删了与绑定交叉的从节点，之后计算没有出现报错。
