abaqus 过约束问题

各位前辈 想请教一下在相互作用中出现的过约束问题如何快速的解决21 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. 望各位高手不吝赐教！
