74 nodes are used more than once as a slave node in *TIE keyword. These constraints are not removed either due to the presence of *CONSTRAINT CONTROLS,NO CHANGES keyword or because removing the constraints might affect the model. The nodes have been identified in node set ErrNodeOverconTieSlave.
tie连接定义有问题， 你在后处理中找到提示的节点集合，仔细检查节点定义是否出现了问题
