我在模擬基坑開挖時，圍護(hù)結(jié)構(gòu)地連墻底面與土用tie的連接，運(yùn)行時出現(xiàn)錯誤：1 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.

4 *TIE dependent nodes have specified boundary conditions.  Their associated *TIE independent nodes have, however, conflicting boundary conditions. Please resolve these conflicting boundary conditions. The *TIE dependent and independent nodes have been identified in node set WarnNodeOverconBoundTieInc.
