1008 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.

840 nodes may not be used with a multi-point constraint since they are also part of pretension section. The nodes have been identified in node set ErrNodeMPCPretenSec.
